Hello! I am preparing myself to make a purchase of a 17" MBP, and I just want to get a few thoughts of mine cleared up before I sink a large sum of money into it. My main fear is that a 17" laptop is a bit... clunky. I won't be transporting it around too much, but I would like to be able to sit it on my lap, or use it while I lay in bed without feel like I've got some big beast sitting on me. Does it ever get too hot to use in that type of position? Thanks for your input, cheers!
