I saw this via Loren Brichter on Twitter. Billed as "The new era of touch spreadsheets. Starting on iPad.", Permanent (App Store link, currently 50% for launch at $9.99) looks like an interesting app to pick up if you're doing a lot of spreadsheeting. Spreadsheets? Number crunching on your iPad.

Planned and upcoming features include Import/Export of CSV and Excel files as well as iCloud, Dropbox, G Drive, & SkyDrive support.
