This 2011 iMac has Photoshop. Kind of a meh for me, but I'm seeing what it's all about. I still prefer IrfanView for web photos because I'm quicker with it. And it's quicker in general.
2011 iMac: Mac packaging is a mess, just like all other packaging. Traditional Mac packaging is great and hides a lot of messy stuff. But now there's the Apple App Store, and lots of free-software developers package stuff differently. It's confusing.
More on the 2011 iMac: I stuffed it with 20 GB RAM a while ago. It has a 1 TB spinning drive buried within. You need to remove the screen to get it out, so that ain't happening. It runs OK. Not better than you'd expect, maybe, but OK.
