Personally from my experiences, laptops are just a pain in the ass.
You expect mobility with it, although you're still really limited. You would need to use a desk in theory, I've had my laptop on my bed sheets/covers many times and it just overheats.
Downsides to your computer overheating is the graphics card actually un-soldering. I would suggest a desktop regardless, and perhaps getting another laptop to use for business and forums use etc.
