I'd like to see iSync become a *real* application that just simple kick butt! First, FIX IT, so it doesn't duplicate things. And if it does, give a window with a list (like a spreadsheet) of all the dups and let me select which one I want. (It kinda does that now... but not well. ) And second, build in support for more things. More cell phones, PDA's, and more information like notes/memos, voice memos, etc. Just make is a more robust application.
How Could OS X Be Improved?
