Samsung R610

Bought me one of these off Ebuyer for £510 including P&P.

T5800,
3GB RAM,
250GB HDD,
Nvidia 9200 GO (re: [LIFTED], but dedicated),
1080p, 16" screen,
Blu-ray drive.

Really astounding value at that price. So much so that I bought two! Although to be fair one was for a friend.

I've noticed that ebuyer doesn't do that model any longer, and for the life of me if I could find a place that was that cheap i'd link you to it but all my usual suspects either don't have it or are charging the earth. It's worth looking for it though if you have the time. The build quality is excellent, the keyboard probably the best keyboard i've typed on excluding my G15 and though it has it's faults (no media keys, tinny speakers, crap graphics card) it makes up for it with the lovely little extras like the numberpad included on the keyboard, Draft N wireless and a decent battery life for a relatively powerful spec (about 3.5/4 hours normal use).

The thing is thats similar (lower graphics and less memory but better screen and slightly better cpu) than the £480 Acer (before 5% discount and £20 in vouchers)

I'm holding off for a while though, goign to see if I actually really need one

My Acer Extensa is 2004 vintage and still going strong, the build quality is isn't up to MacBook Pro standards, but it is "good enough". It has never had any problems and the battery still lasts for about 90% of the time it did when new.
