Had a quick search for this and couldn't find it posted. Can be ordered now for stock 17/06/10. Even though the processor is the old line it's a quick one and, except for the slow hard drive, it's a good high spec machine. I must admit i've never owned or used a Vaio but a lot of people swear by the superior build quality and usability (enough to pay the couple of hundered pounds they tend to be over other similar spec laptops). I would imagine building a similar one to this on Dell would be at least this price anyway. Personally I think it's a great looking laptop too. General spec list below.

EDIT: Just for comparison, the same machine with only a 512MB graphics card, no blu-ray and a lower res 17.3" screen is £989.00 on dell.com (It doesn't offer the corresponding upgrades for those bits).
