Looking at getting a used X, can you use the phone to watch a streaming internet webcast, and also run it throught the HDMI output to put it on a HD TV set ?
If you pair it with a VNC server you can control the phone from a PC (or tablet or another phone) while RealHDMI is running. The only big issue is that Gingerbread broke it. A fix is in the works, but no time specified: Welcome to the GmanApps
