But the car is not for sale.
As for locking yourself in, you did that from day one when you started using any proprietary processing (be it Photoshop layers or Reports from Quicken). Nothing from the outside forces you to upgrade either. BUY CS6 and use it as long as you like.
I used to be able to buy the car... I have the year old model call the Adobe CS6. Turbocharged and all that. But I'd like the option to buy a new car a few years down the road. Many if this one no longer gets me from place to place fast enough.
