I am considering purchasing an Apple MacBook Pro for the first time. I have previously always been a loyal PC (mainly Dell) user, but am in the mood to try something different for a change. I had originally ordered an HP Envy 17 3D, but almost immediately regretted it. I was relieved when they told me it was delayed and asked me if I wanted to cancel, which I did. I know that the specs for the top end 15" and 17" MBPs are identical this time around, which actually makes my decision harder. I would normally always go for the top end 17", but now I am wondering if the 15 would be better. Other than the display size, are there any other advantages to the 17"? I'm thinking in terms of heat output, speakers, ports, etc. I really am torn. Any help you could give would be greatly appreciated.
