Maybe this is a market opportunity for somebody to build a laptop with high end components (monitor, keyboard, touchpad) running a super-duper-well-integrated linux.
But - I have to say I preferred the hardware on my old Sony Vaio Pro 13. The Dell keyboard is OK but the action isn't great, the battery life isn't great, and I really miss the extra thinness from having a carbon shell instead of aluminium.
The perfect laptop will exist somewhere, eventually...!
