Macworld.com - Perhaps youâve seen that recent Microsoft demo where a game could save and load progress from Xbox 360, Windows 7 and Windows Phone 7 Series devices. My first thought upon seeing that was âSo, why doesnât Microsoft have something that can do that on Xbox and PC right now?â My second thought was âBoy, wouldnât it be nice if there was something like that for the iPhone and Mac OS X?â It turns out that I wasnât alone.
