OK, we know you're probably iPhone-apped out by now, but a seemingly promising program called DataCase is worth a mention. It turns your iPhone (or iPod Touch) into a handheld wireless drive, meaning you should be able to peek at your PowerPoint document, reread your Word Document, review a PDF, or check your Excel spreadsheet when and where you want, with no upload program or server configuration necessary.
The program works directly with Finder and Bonjour to let you save all manner of files by dragging and dropping. PCs and Linux are also supported.
The application is currently in public beta, with the development team at Veiosoft delaying the final release so they can iron out any major problems. "We expect the beta period to be very short, and sincerely hope you'll understand our desire to release quality software over pushing out something that does not meet your expectations," the Web site says. Hmmm, we like the sound of that. The $7 price tag doesn't sound too bad, either.
Watch a demo of DataCase below.
