The next part is fairly obvious. Storage will cost money. The $79.95 plan (roughly $950 per year), comes with twenty (20) GB of storage. I have episodes of Duane's World that are over 100 GB. How much is this going to cost me? Maybe I archive it locally?
Some good points should be the performance. I will definitely be trying some of the more computationally expensive tasks from the free account to test. Another benefit is that all my files (well 20GB of them) are with me wherever I go.
Adobe has put a lot of thought into this and it will be interesting to see what percentage of CS 5 and 5.5. users actually jump to the cloud or upgrade further. I'm not a good designer (as is obviously by my blog design) and probably cannot make use of most of the features. This makes me happy to stay on 5.5.
I'd like to hear stories from those on the Creative Cloud. What kind of experience are you having?
