Adobe Jumps Into the Mac App Store, Offers Lightroom 4 for $150

After dipping its toes in Apple’s Mac App Store last July by offering Photoshop Elements, Adobe has now jumped in headfirst by listing its professional-caliber program, Lightroom 4. The download costs $150 and tips the scales at 388MB. Adobe might be a giant company, but it gets charged the same commission as any other developer: for every copy sold through the App Store, Apple pockets a cool $45.
