If it could have 100% the feel and look of XP at the keyboard/mouse without the crappy running ability, I’ll switch as soon as I’m able to pony up $1000 for a computer.
$300 Laptop + and you're well on your way!
You do understand that you can use almost any USB mouse or keyboard modern Macs. I really like Logitech wireless keyboards and mice and they work just fine with my Mac Pro.
