How about a laptop with a better key board, slim figure, larger special character keys and more feedback for keys? Then shove a great processor, a mouse pad that's not accidentally click able while typing, and a high resolution screen. That's a developer laptop. Ill install my own software, Thank you very much.
Realforce 87U keyboard
2x (yeah they do exist I think) 1920x1200 screens, perhaps with really high PPI like the new ones Apple is releasing soon.
No touchpad (I'm quite happy with plugging in a mouse), I'd rather use a nipple.
Light, lots of battery, no need for a fancy graphics card. Decent CPU, doesn't have to be extreme.
Tons of memory, 16gb at least, the more the better.
No software at all. I'll install my own distro.
