Well, I think this is absolutely fantastic. Cool transitions combined with sweet interaction surprises, I was delighted with the follow page. Nice Work! This is a great piece of inspiration for myself.

Got my invite yesterday as well. I feel lazy to try it out.

I upgraded while at work and it took like 40 minutes to complete :V. It was an entire day of procrastination, since when I decided to start working the upgrade began as well. I spent 40 minutes thinking of an excuse I didn't have to use. No issues or whatsoever, tho.
