hey i just got my new macbook pro, 15" 2.4 ghz i5 model. I am loving it and it is my first mac so here are my beginner's worries. sorry if they are stupid questions; - Top left and right corners of the trackpad aren't clickable. Is this normal? I hardly can click the top middle part of it. -Computers top left part gets hot. it's not that disturbing with pants but it is summer time and using it with shorts can be disturbing. I will be using this computer for a lot of time so i want to take good are of it. I am checking the heat of it with istat and what should be the ideal heat? after which temperature i should start worrying?
