I don't know what crappy laptops you use but my good laptop is pretty darn solid. Granted I don't do a lot of crazy things on it but it still gets the job done.
Anything you can do on your laptops, my desktop can do about 8x faster, minimally.
It's not about "crappy laptops," it's about the fact that I work faster on a desktop, and the work gets DONE faster, too. Laptops are for surfing the net, IMing, writing papers, and... that's about it. Just because you CAN do most things on a laptop doesn't make it a pleasurable experience to do so. The storage bottleneck alone is hideous.
