Most developers continuously look at their software and provide bug fixes, firmware-compatibility updates, security updates, improvements and enhancements as needed and upon request. The apps may not be compatible with major firmware updates, so they might become worthless if the developers don't update them for the new firmware. I don't mind it at all; I prefer to buy software and apps that aren't abandoned by their developers. You can stick with old versions if you like. Apple doesn't force you to update.
It used to drive me nuts. I also hate the email badge. I always open them to get rid of the badge. I show seven because my kids just emailed me good nights and I returned five redbox movies.
I don't update them because I got tired of the changes that was being made. Unless I'm have a problem with the app I don't update. I will update when iOS 5.1 comes out or I jailbreak.
Me, too. I've had a couple of updates over the years that I regretted doing, but that was easy to fix. You just delete it on your phone and sync. The old version will be synced on when you do this. If you've already synced and have the new version on your computer, you just delete the app on your phone, grab the .ipa out of the trash can and drag it into iTunes and then sync. I'm not going to miss out on all of the helpful updates when there is a solution for the rare occasion that one sucks.
So why not update then? The only preventative maintenance involved is not emptying your trash until you've tested the apps. I'd rather have garbage in the trash than outdated versions of most of my apps. Most of them are either beneficial or neutral. The other option is to grab them all out of the trash can and hang onto them, but I'm top lazy to do that.
I used to be that way. Am that way with every thing. I had a run of bad updates that changed things that I liked. Or added thing I didn't like. So I stopped updating. Plus I have only not been updating since Xmas.
Updates can be a pain in the pattute but at least the iPhone makes it easy to select "Update All" and get it done quickly. If you're connected over WiFi when you do the updates it goes very fast, and of course you can continue to do other things while the phone updates your apps.
