I agree with Ghengis. Laptops are a pain in the bum. I use one all the time, but only because I have to move around. On the desk next to me in our home office is a desktop we have had for five years. During that time we have upgraded just about everything at one time or another, so it is effectively a new-ish desktop, but we have never a one-off heavy financial outlay. On the other hand, I'm on my third laptop in the same time. None of the laptops have ever had the power or versitility of the desktop and it is very rare that I can do the repairs myself on laptop hardware, but I can take the desktop apart very happily.
If you don't need to move around, get a desktop.
