Hell, these are starting to look interesting. Try to work on some budget models with high end graphics though. I wouldn't mind skimping on the rest of the system if I've got far more graphics power than I expected for the price, as these days with a modern cpu and 2+GB RAM its gonna be the GPU thats the major bottleneck for any gamer in a laptop.
Any 9800GTX laptops go below £1000, or any 9800GTS below £800 and damn I'll be sorely tempted, and if you could manage it you'd probably steal a fair chunk of customers from the gaming laptop manufacturers.
Might not be possible, but given the reputation Dell have for giving massive discounts on some of their gear on occassion, I'd imagine a high end mobile GPU is achievable more affordably than most would expect, and the market is there for exploit; weaker overall machine with high end gpu, normally it's all high or nothing; and I'm sure you'd rather sell a higher load with a slightly smaller margin than a low amount with high margin (depending on figures ofc!)
