Fair enough. But a basic laptop,such as the one I'm using now, from a PC refurb store? £162. (And it's not all that basic, 15.6" screen, 320GB drive, 3GB RAM, cheapo dual core processor, reasonable make). There's a reason why well over 90% of all computers are PCs. Simple economics.
I've bough hundreds of laptops through work over the years. For reliability, Lenovo are currently the best bet. Toshiba used to be great, but have slipped a bit recently. Dell pretty good, cheap and surprisingly OK to deal with. Sony Vaio, Compaq and HP all OK but certaibly not worth paying a premium for.
Have a look in the computers section of HotUKDeals. Lots of links to good offers there. Just take the forum comments with a pinch of salt.
