One app I'd be interested in seeing on the iPad would be the BOINC manager (http://boinc.berkeley.edu). I wouldn't be surprised if it won't happen considering it might be considered interpreted code & it's best used as a background app which is a big no-no in the eyes of Apple. Plus, it'll drain battery life like no one's business. I'd just be interested in seeing how quickly an iPad would compute things. And considering how many iPads (and by extension iPhones & iPod Touches if they get this app) Apple thinks it'll ship, that should bring quite a bit of computing power. As I said, never gonna happen, but still an interesting concept.
