For me, it wasn't TOO laggy (Macbook Pro 2.4 GHz running the 'Ezra' Flash 10.1 betas). That said, the flash viewer scrolled FAR too fast, and was very flickery.

For me, it wasn't TOO laggy (Macbook Pro 2.4 GHz running the 'Ezra' Flash 10.1 betas). That said, the flash viewer scrolled FAR too fast, and was very flickery. It was impossible for me to trackpad-scroll to the bottom of a page without ending up three pages down. My question is, why would I want a document collaboration system that I can't use at all on an iPhone or iPad (even in view-only mode), when other solutions like Google Docs work (to my knowledge) quite well?
