Just not worth it. As others said, I get almost just as much for $50 less with 2 prem accounts now. Being a creator, the free uploads are a nice thought, but honestly not nearly enough to justify the extra an make me to want to change.
Just wondering as I haven't tried again for ages, but is the beta grid working again? After a bug they had my login there got borked and they have been promising to fix the bug with it now for over a year.
Unless you use Android of course. Then you have access to the Lumiya viewer, which is an amazing feature set (incl full 3D view)for a mobile implementation.
