Nick,
Thanks for the suggestion. It is not as convenient to switch to another computer in the middle of a project as to just switch apps on the same computer, but for me it's more convenient that upgrading some very expensive software.
Chas_m,
Thank you for the Pixelmator suggestion. I will look at it but I can still use good old CS2 on my MacBookPro.
Even though you say, "Not to be rude," I still found your statement "If you're not prepared to do that, don't make the initial investment," to be exactly that.
A somewhat bold and arrogant statement to someone whose situation you do not know. As a video professional, I purchased every upgrade of Photoshop from Adobe since version 3 as well as every other app that I needed to do my business; hundreds if not thousands of dollars per year. I was forced out of business in 2008 due to a back injury and do not currently have the ability to simply upgrade it all when the hardware changes.
I imagine that you or anyone else is unpleasantly surprised when a software application, no matter how old, was working perfectly with one version of an operating system and then suddenly doesn't with the next upgrade. I don't find that reaction at all unprofessional.
So. I do appreciate that you made a reply and a suggested an alternative application, it was just your condescending sentence that I found offensive.
