So I got Numbers, and after spending about 3 hours working on a Numbers spreadsheet on my iMac, I was greeted with a message on how the iPad Numbers can't do a ton of stuff, mainly drop down menus, merged cells, etc... So I started looking at some of the other options out there. Namely Documents to Go, and QuickOffice. Both look like they "do" Excel files, but what app actually runs a spreadsheet like it's supposed to be? I want to be able to handle all my attendance/records/invoicing (as a private music teacher) inside the iPad itself. I'd build the file on the desktop as that'd be tons easier, but then I'd want it to actually work on the iPad.
