It certainly has been a busy few days for "official" apps. You know, the ones from big names stores, media companies, services, etc that have come to define modern commerce. Yesterday we saw Best Buy and Amazon.com Fresh (a WP7 exclusive) and in addition there were more that we missed:

Personally, we're excited about Eventful--that app is pretty awesome (though a bit overwhelming in Manhattan!). Combined with Angry Birds, Kik Messenger, AllRecipes.com and the Colber Report's The Word and we sure have a packed house. And it's only Wednesday. (Thanks, @MajorCrash, Shane S., & Larry B., for the heads up!)
