Is there a comparison between this and the standard Pixelmator somewhere?
I've been happy with Pixelmator ... I suppose I can't blame them for wanting to continue to monetize their product. Seems like the app store doesn't have a way to have paid upgrades (e.g. v2 to v3). However it probably means the existing Pixelmator probably won't get any new updates aside from fixes.
I also would like to see what's different/new in the Pro version, but I'll probably upgrade anyway.
Also, I believe the $59 is a sale price, and will go up to $99 after new features are added into later updates.
