But man, for a hacker, the Pre is incredible. As mentioned, it runs unsigned firmware and has a root shell over USB when in developer mode (you can use the Konami cheat code to enable dev mode, too); you can do whatever the hell you like to the OS! The entire UI and all the apps are written in javascript, which in essence means the source code is available for you to modify at will, without recompiling anything. Even better, you can write C/C++ native Linux apps for it that draw directly to the framebuffer, as the recent Doom port shows.
