Wasn't overly cheap (£749) but what impressed me was the quality of the screen: I currently use my daughter's dell and I find it quite dim. The advent was really bright and looked as good as, if not better than, the other significantly more expensive units there (I know set up can vary).
It had a reasonable processor, a slightly small hard drive (40gb) but it seemed to strike a reasonable balance of size against function. I find my daughter's dell to be quite sizeable and was looking for something more compact.
I was initially going to get an iBook, the 12" model but there are two things that concern me about it: firstly the screen is again not too bright, very much like the dell, secondly it features accelleration on the trackpad which I'm finding a little awkward to use after using non accellerated PC trackpads.
I was hoping that someone here would have bought one as I'm concerned about battery life etc as the iBook will last for ages on a charge (and it does have OS X).
I find it irritating that I can't find out any further tech specs on the advent. It makes me concerned about finding more about it should things go wrong with it.
EDIT: just managed to find it on the Curry's website. I took the number down incorrectly, it was a 7078. The only problem I can see with it is they reckon the battery will only last just over an hour: that's no good at all
