Krita actually resembles Photoshop quite a lot, and while the feature list is impressive, I don't think it replaces Photoshop 1:1 or is even meant too for that matter. Krita is more aimed at digital painting, Photoshop isn't a digital painting application, if anything, that's what Illustrator is for.
For a free application you have to give props to Krita, it looks fantastic and plenty of digital artists and illustrators have been raving on about how great it is since it came out. It definitely appeals to me more than Gimp, but I would still probably use Gimp over Krita for general photo touching and editing though. Even the about page on the Krita site itself speaks of illustrators and more drawing purposes. I mean if it works as a Photoshop replacement for some, then that's great. Undoubtedly a cool application.
