Price is always an issue with these things. For one, even if it came from a big company like Nintendo or Sony, you are not sure it will survive and have good games released. By the time you realize that, the next new thing has come out and the previous model looks "eh" in comparison, though while still awesome it is just not that interesting anymore.

Something open source like this is even a wilder betting game. What if devs don't attach to it? The Pandora obviously has a robust development community for an arguably small market. That makes it rather interesting to me.
