GoodReader for iPad (and iPhone) continues to get better all of the time. It's the ugly Swiss Army Knife of iOS. AFP with Bonjour discovery makes it a simple process to get to files on a local network without needing to jump between the computer and the iPad. GoodReader can also connect to a Time Capsule over AFP. There's also iCloud publishing and the ability to unRAR an archive. Too many great features to list here. I can't wait to try these out. Go get it if you don't already own it.
