Okay, so the video showing the new repair tool does seem to be a little too good to be true but in use, the new repair is actually very powerful with impressive results - better than I was expecting.
Now, I would love to the see a Pixelmator version hit the iPad. I know it won't be able to offer the same kind of power as a desktop equivalent but it seems all the best image editing apps for iPad are all from smaller, less well known developers and I genuinely see a gap here for a bigger, more established name.
Some of the apps for iPad are very capable indeed but I would love to have a similar product experience between the Mac and iPad with a single app.
