What is a Netbook?

The wikipedia has the following to say about the term “netbook”

“A netbook is a very small, light-weight, low-cost, energy-efficient laptop, primarily used for internet based services such as web browsing, e-mailing and instant messaging. They are also suitable for light use running office and educational software although they lack the power of more expensive subnotebook PCs.”

Why buy a netbook?

This article will help you decide on the right Netbook for you, or indeed whether a Netbook is right for you!

What do I want to use if for?

The first question to ask yourself before purchasing a Netbook is “What do I want to use it for?”. The answer to this will greatly influence your choice of Netbooks.

Netbooks have been designed to offer great portability, but this is at the loss of other functions such as processing power, memory and storage space. I discuss below the suitability of the average Netbook for a number of common computing tasks that you might involve yourself with.

Netbooks traditionally come with either Microsoft Windows XP or a flavor of Linux. This author owns a ASUS Eeepc 904 HD with Windows XP, and so the following discussion is based predominantly on his experiences with a Microsoft based Netbook.

Whilst the Linux Netbooks are often cheaper, if you are not familiar with the Linux operating system, you may be better rewarded by spending slightly more on an operating system that you are comfortable with!

Music editing / production

Music editing and production typically requires specialist and often expensive software to get the best results. These pieces of software typically consume a large amount of RAM and can use a lot of processing power as they perform complicated computing tasks to produce high fidelity sounds and effects.

Arranging of medium to large scores also consumes a lot of RAM as sound assets are often stored in memory as they are being manipulated.

Samples and virtual instruments can often take a large amount of disk space, and certainly the higher fidelity sounds and samples that you wish to operate on, the more disk space you will consume.

The quality of sound hardware in Netbooks is rarely up to the high standards offered by most of today’s higher end laptops and certainly below that of dedicated sound cards found in modern desktop PCs. It is netbookexperts opinion that your average Netbook is not at all suitable for any remotely serious audio editing and production purposes.

The author has attempted running fruity loops studio on his ASUS Eeepc 904 HD, with less than satisfactory results! Mind you, you are unlikely to want to listen to the garbage he comes out with even on a high powered desktop!

Graphic design

Graphic design software such as Adobe Photoshop typically requires a large amount of RAM to deliver adequate performance, coupled with this, graphic design soon requires a large amount of storage space as file formats such as Adobe Photoshop’s .psd format quickly grow to rather large sizes.

Graphic design is also benefited by a large screen, to allow the designer to better visualize and organize his / her creations. Most Netbooks have a rather small screen (7 Inches – 12 Inches).

Due to the average Netbook lacking in storage space and RAM in comparison to your average desktop, it is this authors opinion that most Netbooks would not make a good mobile computing platform for a graphic designer.

The author does himself use Adobe Photoshop on his Netbook, and this has often been the cause of much frustration as a lot of scrolling around the canvas and a lot of waiting occur!

Games

Today’s games require a lot of processing power, usually an optical media drive (CD / DVD), high fidelity sound, lots of RAM and frequently a large amount of hard disk space!

Your average Netbook is really not suited to offer an adequate gaming experience! the author does however run Trackmania Nations on his ASUS Eeepc 904 HD, and has a great time when the graphics options are turned down a little! Today’s games are really best played on a higher end desktop PC or a higher end laptop designed for gaming!

Office documents

Whilst Microsoft’s office and open office require a moderate amount of RAM and hard disk space, your average Netbook is more than capable of dealing with their demands and makes a great mobile office platform for the traveling salesman or remote worker!

If you are going to be authoring a large number of documents, then you should consider the storage space available when purchasing a Netbook.

A lot of Netbooks come with a VGA port, allowing you to plug in a projector to present your PowerPoint presentations or a CRT / Flat screen for a slightly less cramped working environment.

Music playing

Whilst your average Netbook does not contain the highest end sound hardware, they are usually perfectly adequate for running Itunes or the likes of Spotify to keep you from boredom whilst working.

The headphone jack available on most Netbooks can be plugged into headphones or a HiFi to a better sound than the often low standard built in speakers! The author has plugged his Netbook into his HiFi and whilst the sound quality is not great, it is perfectly acceptable for most occasions!

Web browsing

The average Netbook is the perfect tool for browsing the web on the move! The author plugs his into his O2 PDA and uses the 3G connection from the phone to browse the internet!

Screen size can become an issue on larger sites, but tools in Firefox and IE allowing you to zoom in and out, or change the sizing of a website can be a great help! Performance can be degraded by having lots of tabs open, due to lack of RAM, but for most purposes, the average Netbook performs admirably!

Coding

Developing applications can often involve the use of a large number of different tools and complex development environments, these usually consume a fair amount of Hard disk and RAM. It is the opinion of this author that your average Netbook is not the most suitable computer for a serious development platform.

The author however comfortably runs Microsoft Visual Studio 2005, Mysql databases and a number of other tools on his Netbook – a very handy mobile development platform!

Watching films

Watching films or video usually requires the use of an optical drive such as a CD or DVD player. These very rarely come with the average Netbook, limiting the ability to watch a good film on them!

You can generally pick up cheap USB external CD / DVD player for under £70, but with the small screen area of most Netbooks, they do not make the best home entertainment platform.

Watching online video, YouTube etc, is absolutely fine, as the smaller video size and lower fidelity of the content is perfectly suited for watching on a Netbook, your average Netbook does indeed make the perfect platform for wasting a large amount of your morning browsing entertaining videos on YouTube!

Mobile Broadband Products & Services

Introduction

The principle attractions of mobile broadband technology are flexibility, convenience and, of course, mobility. These features, coupled with the fact that the mobile voice market is saturated, meaning that providers are forced to offer competitive capped data packages, means that the technology has quickly gathered pace. In fact, mobile broadband prices fell by 4% in 2008 compared with 2007, if all countries were taken into account, while, in the U.K., prices fell by as much 35% in the same period.

The number of mobile broadband subscribers in Europe increased to nearly 20 million in 2008, thanks to the availability of user-friendly USB (”Universal Serial Bus”) modems, or “dongles”, and new developments, such as HSDPA, “High Speed Downlink Packet Access” technology may see the total number of connections reach 150 million by 2014.

Mobile Broadband Products & Providers

Mobile broadband works in the same way as landline, or cable, broadband, insofar as subscribers sign a contract, typically of 12, 18 or 24 months` duration, and pay a monthly fee for their chosen mobile broadband package. Mobile broadband is available from 3, Orange, T-Mobile, and Vodafone, and prices vary between providers, with speed, monthly download limit, and minimum contract length determining the price of individual packages. Most mobile broadband packages include a USB modem, invariably free of charge these days, which contains a SIM (”Subscriber Identity Module”) and plugs into a laptop computer.

Download speeds of up to 7.2Mbps (”Megabits per second”), which compare favourably with fixed line broadband deals, are possible, but monthly download limits are must more restrictive, typically between 1Gb and 10Gb per month, and 3Gb per month on average. Unlike fixed line broadband deals, where “unlimited” download limits are commonplace, if you`re prepared to pay extra for the privilege, mobile Internet deals must take into account the finite capacity of 3G (”3rd Generation”) mobile phone networks, and the cost of transferring data across them.

Unlimited download limits would place unacceptable strain on the 3G network, leading to slow service and dropped connections, not to mention the high cost of data transfer, when compared to conventional ADSL (”Asymmetric Digital Subscriber Line”) or cable broadband connections. These are the factors that are likely to limit the growth of mobile broadband in the short-term – not withstanding the current global economic downturn – but with 3.5G, and 4G, technologies, such as HSDPA, and WiMax, driving the market ever forward, that may not always be the case.

Quick data visualisation , in-cell bar graphs

Quick data visualisation , in-cell bar graphs.
Spotting trends in large volumes of data can be tricky! Thankfully Office 2007 introduces a feature that allows you to format columns of data
according to their value, allowing you to see at a glance the distribution of data and any significant outliers!
Illustrated here is a sample of data in two columns. To visualise the data in the second column:
1. Select the contents of the column
2. Select the “Home” tab in Excel 2007
3. Click “Conditional formatting”
4. Click “Data bars”
5. Select a colour scheme to suit your taste!
The visualisation will appear as below. Helpful huh?

You can customise the colours and rules by which the cells are formatted by clicking the “More Rules..” button in the data bars menu.

If you don’t have Excel 2007 – not to worry! There is a work around for previous versions of excel, one of which can be found here:
