In reply to EdS:
I bought the cheapest one you could get from Curry's about a year to 18 months ago and would describe it as "not brilliant, but usable". It does work for browsing the internet and such, but it's much slower than a decent laptop or something, the battery life is decent though. Basically my lesson learned is that if you want it to be fast and slick then you can't get the cheapest one. I think for sure if you spent the corresponding amount on new laptop though it would be awful.
I had a different one probably almost 10 years ago when they first came out and that was faster than this new one and lasted us years, and that was the cheapest at the time as well.
Could be worth checking if CEX sell any as they do 2 year warranty's on everything and you can return to a store within 14 days if you order online, some of the laptop prices are much, much lower than the "new" price (obviously it varies and it will be used already so you might not like the idea), and disclaimer I've never bought anything from there have just been looking on it recently at laptops.
