1. I will wait for a few point releases to even test the waters.
2. I still have a 1tb TimeCrapsule, backs up the 3 macbooks no problem.
3. I've managed to build up 12+tb storage in the house, I don't care about smaller formats for pix and vids at this time.*
4. Bottom line, nothing to see in this update.
*Glad to see development of this in any case.
