I am a full time graphic designer working for a company, but I do some work from home and a bit of freelance now and then. This idea of renting software by the month is a disaster, I currently own CS4 at home and thats where I will have to stay. Not only that, but I have found CS6 to be very buggy, with no perceivable improvements of the last version,
CS5 was much more stable. This is why competition is a good thing.
