There's no bigger software ecosystem than a laptop running Windows that can be converted into a laptop running a Linux distro.

But, you've got me on the 'best displays' portion. I think the iPads have 120hz displays? They're amazing and threre's nothing like them. They most certainly are "all that", but despite having the opportunity and the spare cash, I still prefer the trashy, ghosting, dim, low-rez display that I have attached to a real laptop.
