Review: iPhoto for iOS out-does Adobe for mobile image editing: Apple released the final piece of its iLife suite for iOS on March 7, delivering a universal version of iPhoto for iPad and iPhone (sorry, iPod touch users). We spent some quality time with the app using an iPad 2 and iPhone 4, and came away impressed with the unique user interface design, general intuitiveness, and overall power Apple managed to pack into the app.
The app has a lot more photo tweaking capability than you might expect from first blush, including fully non-destructive editing that can be selectively undone. It also improves a bit on the standard Photos app's organization, and greatly enhances sharing options. More importantly, for $4.99 you get a photo editing tool that can, in many ways, out-Photoshop Adobe's own Photoshop Touch.
