I downloaded the preview and I'm testing it out. I notice it doesn't even try to conform to the Mac interface, which I'm not very sure I like, but it isn't necessarily a show-stopper.
I've been considering a number of alternatives, but I have a number of Photoshop files laying around, and it's nice to have Photoshop compatibility.
However, several things concern me:
How good of an image editor/creator is this compared to the full fledged Photoshop?
Does it have full Photoshop compatibility?
I understand it can't do CMYK color. So what do I do if I want an image printed?
And-- Activation. This concerns me. Is this going to make my Mac spy on me, and make my life difficult every hardware and software upgrade?
I don't have any kind of professional need for Photoshop. It's just a hobby for me, and most of the work I do is for the web and computer, so CMYK is not a necessity. However, I do occasionally design something for print, such as business cards. Sure, it's not $400 + we're talking about here any more, but even at $80, I'd like to know what this can do and if it's worth it for me.
