So, let me suggest the "Mindful" way of updating your apps. When you see you have updates, hang on until you have time to give the updates page a little skim:
|If you want to selectively update apps, iOS6 makes this much easier by not kicking you to the home screen every time you tap Update. Nice!|
Skimming will allow you to view what is new with each app (sometimes you have to tap More to see this content). Why does this matter? Recently, for a few examples, the "skim" showed me that Toontastic had added a new series of playsets, My Playhome a parents' bedroom, Bag Game and Social Adventures had added the ability to add your own pictures to the bag (now for limitless contexts) and lessons, respectively, and Skitch a new interface that everyone apparently hates.
This all has to do with Appy-Picking because we make informed choices each day about which apps to employ for clinical purposes. New content and features in our apps should absolutely influence those choices!
