If Adobe actually goes thru with this, then Pixelmator @$15 and GIMP at $0 will suddenly be very very popular.
Here's an article that compares Pixelmator and "claims" it's a reasonable substitute for PS.
Pixelmator 2.2 is a legitimate Photoshop replacement that costs $15 | ZDNet
And Corel's Aftershot Pro is like $50 or so, cross-platform (Win/Mac/Linux) and you can install it on all your computers. if you don't want to pay, there is also Darktable which I have used on both Mac & Linux. There are alternatives that work very well for a fraction of the price. Oh, and if you need Adobe Illustrator, there is Inkscape for Win/Mac/Linux.
