That doesn't quite answer my question....
I'll assume you are talking about laptops.
your also very limited with a laptop, which also means that you need differnt hardware as well.
Limited? In what way? The fact that you can't change any hardware? Is that really a big deal?
Most average computer-users never go into their machine. If they do, it's usually just to add RAM. You can open up a laptop to change the RAM too.
If you don't need the power, why get a Desktop when a laptop serves your purpose just as well? Desktops take up more room and cannot be moved as easily as a laptop.
