Just an update to this review, having now owned it for 3 months.
I was able to download a very kewl, simple little update for the fan noise, so it's essentially never on and i have a silent machine. The only exception is when I'm stressing the CPU out (like trying to make it play high-def content

)
The trackpad remained rubbish, but a purchase of a £10 Logitech wireless travel mouse sorted that out perfectly.
I'd still like the idea of upgrading the RAM, haven't done so yet, and there are times when apps take a noticeable amount of time to load (ie when running firefox plus Skype, and i try to load up Songbird it can take over 10 seconds).
Pidgin, whilst great at first, has struggled to keep up with the ever-constant updates that Microsoft makes to live messenger, so isn't so useful any more. The annoying thing is, it's all Microsoft's fault

Oh, and the battery could be better i suppose, i get around 3 hours ish, however i simply leave it plugged in most of the time.
It remains a great purchase, and i still haven't seen it for as cheap as that since i bought it.
