I think what I love best about my Palm Pre is that I never have to plug it in to anything, ever. There's a great podcast app that I use twice a day on average, similar to the one Apple infamously rejected, that lets me download them over wifi via RSS, or stream them over EVDO if it pops up when I'm already out and about. Zumodrive's new app means I can stream my entire music library. The Touchstone means I don't even have to plug it in to charge.<p>I think Apple will figure this out and add it to the device themselves eventually. Cords suck.
I don't know what the developers expect to get out of this. Do they think that it hasn't occurred to Apple's engineers that this might be convenient? I think, as with copy/paste and background apps, the issue has been how to implement something like this and not harm the user experience.<p>I suspect the big thing preventing wireless sync until now has been the lack of 802.11n on the iPhone. Syncing 4 gigs of movies out to your phone on 802.11g has got to be painful (and a realy battery drain).
Let me walk a mile in Apple's shoes: If they approve this app consisting of what appear to be a couple of cups connected by networking string, what happens if 10,000 people buy it and some future iPhone or iTunes revision breaks the app.<p>Does everybody blame themselves for buying the app? Or do they complain about the iPhone?
The one thing I wonder about is disconnecting during the sync. A couple of times I have disconnected iPod Nanos during sync and had to restore them. It wasn't much more than a nuisance, admittedly, but on a slower sync with more data transfer (say 20 or 30 GB of video), the likelihood of disconnects being a problem may become significant.
Active discussion of this with the developer posting on reddit: <a href="http://www.reddit.com/r/apple/comments/bvzzt/hey_reddit_i_made_an_app_that_lets_you_wirelessly/" rel="nofollow">http://www.reddit.com/r/apple/comments/bvzzt/hey_reddit_i_ma...</a>
I have a tangential question - if this app was rejected, what is to stop the developer from setting up a website with the source to download, and maybe a paypal donation link (were he so inclined)? Do you have the pay the apple $99 developer fee to even install an app you developed on your iPhone? Or can you do it as long as you have the dev tools installed? I know this isn't an option for everyone, but is it possible?
