OK, here's another one, but this time under the "magic" £400 barrier. Exceptional spec for the money. This is a model identified as having one of the best bang-per-buck when new (October 2008) at full price (>£600) but has since been discontinued by Acer. At £400 this is a better laptop than you will get anywhere - the only possible downside is that it is a refurbished model. It is, however, factory refurbished and mine is as-new.
Don't forget 2% Quidco.
Main specs from my received unit:
Intel® Core 2 Duo P7350 (2.0 GHz, 1066MHz FSB, 3MB L2 Cache)
15.4" WXGA Acer CrystalBrite LCD TFT
3GB RAM (2GBx1 + 1GBx1)
250GB 5400rpm SATA Hard Disk Drive
8X DVD-Super Multi double-layer drive
NVIDIA® GeForce® 9600M GT 512MB VRAM
Intel® Wireless WiFi Link 5100/5300 (dual-band quad-mode 802.11a/b/g/Draft-N)
6 cell Li-ion Battery
5 in 1 card reader (SD), (MMC), (MS), (MS PRO), (XD)
1.0 MP Crystal Eye Webcam
Though this is listed on the Dabs website as having a T5750 the unit I received has a P7350 - a vastly better chip.
Edit 2: It's now £373.84.
