I use Stagemix as well. It just needs more functionality. For other remote duties (using an iPad VNCed to a MacBook Pro for system measurement or tablet mixing), PocketCloud works well for me. (BTW, tablet mixing ain't what it's cracked up to be...)
I use Evernote and Documents to Go, but rumor has it that Microsoft is preparing an iPad version of MS Office. I was trying to use the iPad remoted to my office desktop box as a way to do paperless picklists in Excel (checking off gear as it's pulled and loaded), but it's pretty clumsy and not (yet) really effective. I'm still working on it (when time allows) and having Excel and not an iPad knock-off app might help. Okay, I'll fess up, it's more likely my ineptness with Excel and the other apps that's really the problem.
Fun stuff...
