I was in the presentation of CS5.5 when they introduced the monthly and yearly subscription. I thought it was a great idea and a step in the right direction. Still, while the price per product didn't look too bad and seemed reasonable, when you added 2 or 3 to the list, the subscription was a bit pricely (I don't know the prices now, this was then). Although Adobe products are very expensive, the monthly fees added up almost to the price of the standard version of the software in one year.
Then, I decided that it was not for me and that I would wait a bit longer. I haven't looked into CS6 but I will and I'll see if this could be the right choice for me or not.
I use photoshop everyday amd Acrobat, but I also use InDesign and Illustrator quite often and Flash from time to time. There are some other software that I'm interested too.
