Margie, I'm with you. I'm in several Photoshop groups on Facebook, and it seems as if most of the new version is primarily for photographers, because the discussions are usually about Photoshop AND Lightroom. There are a few upgrades to content aware, but I didn't find them impressive enough to make me want to spend the extra money for CS6. Since IM and I are retired and on a fixed income, I suspect this is the end of the line for me with Photoshop upgrades, too.
I only hope that Adobe doesn't conspire with Apple to make the older Operating Systems incompatible with software like Acrobat and other necessary software. I've already run into my automatic upgrade notice advising me that some upgrades won't be compatible with my "old" operating system (I'm running Snow Leopard). Fortunately, my son the techie can keep me as updated as possible with the Operating System - until my version of Photoshop is no longer compatible with that.
I suspect it won't be long before our only option if we want to upgrade will be to lease the software at a monthly fee (right now it's $49). Hannie, I think you're right. Greed is the key to what's happening, and it won't be long until only high-end photographers and businesses will be able to afford to upgrade.
