Want to save a whiteboard diagram for future reference? Keep your receipts for the accounting department? Photocopy a document when there's no copier around? You can do all that and more with Scanner Pro, which can save and send documents in PDF and JPEG formats, upload "scans" to sites like Google Docs and Evernote, and use iCloud to sync everything across your devices. This ridiculously handy app sells for $6.99.
Hey, Dropbox. While you weren't looking, SugarSync ate your lunch. This cloud-storage tool, soon to get a major update, offers 5GB of free storage, while Dropbox still limits you to 2GB. The iPad app affords full access to your files, photos, and music (complete with streaming), and lets you easily share your stuff via email. But the biggest plus happens on the desktop: you can sync any file or folder, not just the ones you drag into a bucket.
