I've never owned anything by HP, I like basically everything Samsung have ever made when it comes to laptops.
Filtering on expert reviews according to the following: £250-500; 5*; 12"+; W7, the first one
http://www.expertreviews.co.uk/lapto...spire-v3-571/2 looks pretty good, as does
http://www.expertreviews.co.uk/lapto...pavilion-dv6/2. Obviously you have to look at the date of the product, a product reviewed 2 years ago is going to be nowhere near as good as one reviewed yesterday; the next step is to corroborate with another source, just in case other people think it's awful; for the first,
this is the only other review I can find given the product appears to have come out very recently; at least it's not a commercial review (i.e. they want to talk the product up so you'll buy it from them). For the 2nd, I can't actually find any other useful reviews.
In any case. I do enjoy doing this but this is blind, I don't know your requirements (mobility, processor power, battery capacity, screen quality, keyboard quality, connectivity, etc etc) so I'm just looking for a generically good laptop for a poker player. I find that spending some time doing this yourself means you can be very satisfied with your purchases.
