Okay, so in July I am due to have my MacBook Pro replaced. On my desk at work I am currently running a MacBook Pro 15" and on a laptop stand and a 24" LED Cinema Display. I am really struggling if I want a between a 15" and a 17" laptop. This is my 4th 15" MacBook and I know the safe way for me to go is another 15" MacBook Pro. But I use my laptop with the 24" screen as a dual display and I think it would be great to have a larger laptop screen. Also when working in the field it would be nice to have the bigger screen. My concerns are carrying it around and going on trips with it. So my question to those who have had, or have one.. specially to those who went from a 15 to a 17; is it a real pain? Does it get in the way? Too bulky? Any insight would be greatly appreciated.
