pcworth: My Photoshop alternative of choice right now is Flying Meat's Acorn. It has similar features to Pixelmator, but feels more pleasing and fluid to use. I have not done a side-by-side comparison of features, but it covers pretty much what I need. It will open Photoshop files and costs about $30.
Having said that, I still think Photoshop Elements 11 or newer is the way to go if you are looking for something new. Its group shot tool alone makes it worth the purchase price.
Yeah. I'm surprised Acorn didn't get a mention and something like Aperture did; Aperture appears, like most things OS X, not to be on Apple's radar anymore.
deleted_081301: I expext they will do a Micro four thirds version alsowhen they get "Around touit" ;)
Exactly. It seems like a weird omission, since they'd just have to offer a different mount.
