Hi guys, I was looking around at netbooks, and i had a go on the AAO531 in pcworld the other day and i quite liked it opposed to other models, anyone know any disadvantages with this model before i go ahead and buy it? And can anyone confirm whether or not it comes with bluetooth built-in? Different websites seem to give different specs (I'm quite sure they aren't the 'Pro' model). The reason i was looking at the 531 was because i much prefer the design over the d250. Any info will be appreciated guys, thanks!
