I still remember when I had the Moment, we were all eagerly anticipating the coming of flash to our phones with 2.1 on the horizon... then struck down violently as we were told our phones processor couldn't handle it. NOW, with a superphone that actually runs it acceptably, people like OP cry about it not being super fluid and flawless.
I can say, yes, it would be nice if it ran as smooth as it does on my computer, but we're not QUITE there yet. For now, just enjoy it as it is, and realize that you have actual full flash running in your phone, allowing you to do things other people can only wish to do on their devices.
I hate having to resort to that, but its about the best I can tell you, guy.
The grass is always greener on the other side.
