I have owned this laptop for over 2 years now and am very impressed with it, although the laptops CPU is not that powerful compared to other newer dual core CPU's it still stands up to today's applications with ease. Over the 2 years the only upgrades I have made is to increase the RAM from 1gb to 2gb as in the last 6 months or so 1gb was just not enough and the usage was over 90% most of the time, however if you are not looking to play the latest games then the 1gb of ram should be plenty.
One of the great features of this laptop is the excellent battery life, when unplugged and in power saver mode it easily lasts 4hours and even after 2 years of heavy use it will still last 2.5-3hours now. It is also very thin and quite light so is very portable even with the wide-screen.
Some other features that make this laptop a good buy are the built in 1.3mp web cam and microphone (at the top of the screen) and the high screen which gives great contrast and looks very nice compared to other laptop screens. The speakers are also a lot better than the normal laptop 'tinny' speakers and have surprisingly good quality output and volume.
As good as this laptop is I have had a few problems with it over the last 2 years which luckily the 2 year warranty that came as standard covered and Asus fixed it quite quickly, the first problem I had was after around a year when the back light for the screen failed which was due to a wire breaking that feeds from the laptop up to the screen. The second time I had to send it away for repair was just before the 2 year mark when the power supply totally failed and also burnt out the motherboard which they replaced for free. Although this does sound like a lot of problems in the first 2 years bear in mind it has been used intensively (pretty much every single day) and being transported to uni and back most days.
Overall I would defiantly recommend getting this laptop if you can pick one up at a bargain price (cheaper than the £798 I paid) though some warranty would be recommended.
