Okay, this is worrying. I synced most of my apps through my iMac, and for some reason, some didn't sync. Never mind, I thought, I'll get them from the app store. The first few downloaded fine, but now I can't get any more to download. They just sit at waiting, and the iPad shows no sign of doing anything (ie the little wheel is not appearing in the status bar). It's not solved by a restart, and deleting the apps and trying again is not working. Also the few updates I have are not working either. Any ideas? Thanks!
