I bought this Comet/Laskys item ie #438189 last week for £449. It is apparently a Comet group specific variant of the 302G25Hn ie "LX.AN60x.160" and Lasksys (who were selling it at £449 last week, now Comet are and Laskys aren't) don't seem to know the detailed specification but based on first hand experience it seems to be half-way between the Acer website listing of the LX.AN40X.471 and LX.AN60X.041 ie does have the Intel 1GB Turbomemory but does NOT have the upgraded 8-cell battery (which is probably the best way around as can't retrofit Turbomemory but can retrofit a new battery when the first expires).
The 302G25Hn was on here 9 months ago (with a GT video system I think) as a 'hot deal' at £800 - I'm presuming the price reductions are due to HD-DVD and end of line for 5920G.

Don't forget opportunity for Quidco cashback at Comet.
It also has a HDMI socket for output to a HDMI display, although personally I'm still having some issues sorting out the right Graphics/hardware driver settings to get it right/compatible with my big Sony TV.
