So the main reason I'm getting a mac is to develop for the iOS platform - iPhone and iPad. Second reason is that my 18.4" Acer is .. more or less dead so I need to replace it. Main programs that I'll be running Photoshop CS5, Cocos2D for iPhone, Unity 3D, Sony Vegas, Flash CS5, Ableton Live. I'll be playing games, though on Windows mostly through one of those programs that .. lets you.. Not really going to play the latest games at max. I mainly play MMOs on my laptop anyway. Anything is better than the 9500M GS that's in my Acer. I was looking at the Macbook Pro 17" with the i7, 4gb ram, 500gb @ 7200 rpm, high-res antiglare widescreen. Just wondering if the 17" is the right choice (along with the i7) or if I should go 15", i5 or maybe 13"
