I need some advice... While commuting I plan to edit photos and videos for a website. An iPad seems like just the thing as I would hate to carry a laptop when I'm out and about. From this thread: http://forums.macrumors.com/showthread.php?t=1345943&highlight=ipad+iphoto it seems iMovie is aabboout the same. Has anyone had a chance to test out iPhoto and other intensive apps on the iPad 2 vs iPad 3? I heard the doubling of ram is mostly to fuel the retina display and the processor is the same speed (but greatly improved GPU). Will I notice a difference in these types of tasks?-> LOTS of iPhoto, some iMovie, and lots of saved/tabbed browsing since I'll be out for extended periods of time. Are my needs justified for an iPad 3 or will the 2 get things done smoothly?
