Aaron gets some hands-on time with the Motorola DROID 4's flavor of Ice Cream Sandwich (and a nicely revamped Motorola UI to boot).  Available now for download, Android 4.0 brings revamped fonts, new folders, Face Unlock, a revised menu structure, and more.  So far, it seems to be a nice upgrade from Gingerbread for Motorola's customers, and packs some useful updates for consumers - not to mention the speed boost.  Google's acquisition of Motorola looks to be paying off in the UI department.
