I’m as surprised as anyone that after all the success of the App Store, most of what’s on my home screen are apps that Apple provides. Essentially, what I keep there are tools for planning my time, navigating, and communicating. I’m tentative about foursquare, which hasn’t proven particularly useful but is fun to update. I’d also prefer not to have Yelp on my home screen, but I do use often enough to warrant the placement. Tweetie 2, Groceries, and Things are all brilliant examples of the best of what an iPhone app can be and I couldn’t have them anywhere other than up front. Trainspotters may note that I keep my apps alphabetized.
