I would say that I'm real fan of RPi and doing several projects on it. But, as I read here in other topics it is not much improvement planned for coming year. Release B with 512Mb is good enough for many things, but I can see in the market other hardware devices with compatible price and bigger functionality.
For example Google TV player BOX has Cortex-A8 1.5G Hz, 1GB RAM, HDMI, WiFI, USB.
They are surely not directed to Open Community as RPi and "closed" devices, but RPi producers should feel some competitors on their back.
It's time to move forward.
