I sure would like to have a desktop in some situations. Right now, I'm pretty happy with my laptop, since I'm not at my house and still have all my stuff, which is always a plus.
But laptops have the major disadvantage of not being able to expand. I'd love to have good sound and other monitors in my computer, but it takes a lot for that, since it's much more expensive to use one external sound card and impossible for me to have more than 2 monitors (i think 3 would be perfect
).
But still, the next computer will be a laptop, if i haven't got the one i have right now, the portability is just something I can't loose over a few other "desires"
