Dell Adamo Onyx seem to be being discounted in £50 steps, it was 650, and I bought mine when they were 600.
The laptop is much faster than you would expect given the spec - I think the standard SSD plays no small part. It's also really well built and one of the slimmest laptops around.
Although they come with Windows Vista, installing Windows 7 from a Dell-branded Windows DVD will activate itself without any further input due to having a SLIC bios ... very nice! You will (obviously) need an external DVD drive to do this ...
Saveonlaptops delivered promptly and i've had no problems with them.
One thing I noticed is that if you put in the service tag on Dell's site, it shows the laptop as having been delivered sometime in August 09, hence out of warranty .. SOL's warranty terms are quite murky at best!
