Yea, it's because of the lack of flash. Tinychat is supposedly coming out with an iPhone/iPad app, but I've yet to see it or hear of any progress. I tried many solutions, like VNC/VPN to my local machine or using an app that basically VPNs you to one of their machines with a browser to use flash. It's not worth it imo. I'm just holding out until they release a solution with Tinychat. I love my ipad.
