I've wanted a 17-inch laptop from Apple since I was still a young lad in the PowerBook days. Now that I've been old enough to have been accruing disposable income for a little while, I'd pounce Apple's web site and buy a 17-inch MacBook Pro in a heartbeat if it released one. Since I have low vision, I've always considered 15 inches ever so slightly too small of a screen size for my liking/comfort. Beyond that, having the extra screen real estate would likely end up being really helpful for software-development workflows. It might take a little while longer for me to save up for it than I'd like, though, since I'd probably go overkill and obscenely future-proof myself by splurging for top specs. (Pats external–drive–booted family mid-2007 aluminum 24" iMac on its metaphorical head. Hang in there, girl, you and OS X 10.11.6 'El Capitan' still have some life left in you yet… — yes, I know I've been spoiled a bit by having a Mac last and be supported for so long.)
