An open letter to RIM has given a look into potentially serious problems with the development process for the BlackBerry PlayBook. Jamie Murai noted that the costs of getting involved were far more expensive than with the iPad or Android. The PlayBook will not only cost $200 for most developers but only covers the first 10 apps; users also need to have a full copy of VMware Fusion or another ISO-friendly virtual machine to run the emulator, which could cost another $80.
