Some devs might not be comfortable with the command line tools available for current BlackBerry development on the PlayBook. The command line tools are great for scripting (which is what I do) but RIM has decided to release a BlackBerry Tablet OS Graphical Aid app to help developers out who like GUI (Graphic User Interfaces). This new Graphical Aid ties into the Adobe Flash Builder to help you easily build Adobe Air apps for the PlayBook. It allows you to build, sign, and deploy apps without touching the command line. Personally I wish they would just do away with the complicated code signing process but this is a nice step.
Currently the Graphic Aid only works on Windows for Adobe Air PlayBook apps but RIM is promising to release Mac OSX and Linux support soon. No word on if they will release a WebWorks version. You can pick up the BlackBerry Tablet OS Graphical Aid app at this link.
