I had wanted to get a Mac, and I thought the MBP would suit my needs best. For the last 4 years I've used a Sony Vaio laptop pretty much as a desktop replacement - it's been on pretty much 24/7. Recently it started to groan under the strain though, getting excessively hot. I managed to fix this by opening it up, leaving an icepack on the processor, and cleaning the fans a bit. However, I suspect this is only a temporary solution, and soon some vital part inside it is going to die. This has led me to thinking that perhaps I need a desktop (not a Mac), since laptops these days simply can't cope with the strain. So I want to ask - is this true of the MBP? Will it be a suitable desktop replacement? I won't be able to replace it for at least another 4 years or so, therefore I really want it to last. Or would I be better off going for a desktop? I don't really want to go down this route because it would mean not getting my first Mac, as I can't afford the Mac Pro, and an iMac wouldn't be enough for me.
