Computer World published this post and cheat sheet for all things Ice Cream Sandwich. Since many phones are moving from 2.x to 4.x, you’re going to want to keep the guide and sheet close to the vest (I recommend saving the post to Evernote, or bookmarking it).
While Android retains many of the features in 2.x, there are a couple of new “game changers” that I’m particularly fond of.
Recent Apps – Android 4.0 removes the “menu” button, but replaces it with the recent apps button. A quick press and you’re quickly multitasking among several applications. However, if your phone has a menu button, like the Motorola Droid Bionic, this will retain some menu features of Android 2.x.
Notifications - ICS add the swipe to remove feature to the notifications drop-down menu. This is a simple way to procrastinate. The drop-down menu is also much more user friendly, and on the Droid Bionic seems to process requests much faster.
Folders - ICS upgrades and “coolnessizes” the ability to store and organize apps in folders. I should have added this in my supe-up your Android post, but this is a quick way to manage and group a variety of applications, rather than to have them clog up your screen. I didn’t particularly care for the older version’s folders, so I rarely used them. Now though, with both my Transformer Pad Infinity and Motorola Droid Bionic running Ice Cream Sandwich, I’m packing more apps into folders because they look cool.
So, if you haven’t already upgraded to Android 4.0, it’s time. For Windows users, the upgrade is like moving from Windows XP to Windows 7. For Mac users, I guess it’s like moving from Windows to Mac.
