Leverage the vast library of Rdio to power your next party soundtrack using Anthm (Free). This unique app lets everyone at your kegger fancy soiree add songs to the playlist, and vote songs up or down to affect their play order. It's like iTunes' DJ feature, without the limitations of your '70s pop-oriented music collection. [Scouted by Sean]
Your iPad 2 just got a little more useful. Apparently aware that Photoshop Express wasn't getting it done for a lot of us, Adobe's upped the editing ante with Photoshop Touch ($10). Also available for the 400 or so Android tablets sold so far, it brings desktop features like layers, selection tools, advanced adjustments, and filters to the tablet, along with plenty of other tricks like the Scribble Selection tool, integrated Google Image Search, and Facebook sharing. Yes, its max resolution of 1600 x 1600 is pretty pathetic given the size of images we deal with these days, but for images that you're planning on sharing via the web or email, it's more than enough.
If you like your iPhone, iPad, or iPod touch, you're going to love Mac OS X Mountain Lion ($TBA). This sequel to last year's Lion ups the iOS-like ante with deep iCloud integration, new — yet totally familiar — additions like Reminders, Notes, and Game Center, as well as a revamped, iMessages-handling iChat — now known as simply Messages — a new Notification Center, Share Sheets, Twitter integration, and AirPlay Mirroring. And knowing Apple, there's probably at least a few new features we haven't heard about yet. Roaring onto a Mac near you this Summer.
