The registration process would be funny if it weren't so frustrating. You get to register not once but three times for App World if Playbook development is your thing. First, the registration for App World itself, which makes sense, except for the part where you have to send in a notarized statement validating your identity. Yes, you read that correctly. Print off the form, fill it in, have it notarized, for a fee of course, and send it to RIM.
Once past that, you have to download the Adobe AIR SDK, the Playbook SDK and Playbook simulator. These aren't one nice download either, but three separated downloads. When downloading the Playbook SDK, you have to go through another registration process, entering again much of the personal information already entered in the App World registration. Finally, when downloading the Playbook simulator, you get to enter your personal information a third time. Makes you wonder if the US military has anything to do with this as they always like things done in triplicate, at least according to Radar.
Now with everything downloaded, getting started, everything should be a snap, right? Wrong. The AIR SDK has no installer, the Playbook simulator requires that you download VMWare Fusion, which costs $80 to register and the simulator from RIM is an ISO file wrapped in an installer for some reason, just to make the process more fun.
You get the idea. At this point, development still cannot begin, but I'll let you read Mr. Murai's adventures for yourself to see how the story continues.
RIM has seen the open letter and responded. In fairness, the development process is in beta, but some of this stuff is a bit much to foist on a developer community they are trying to encourage to fill their store. It never should have made it to the public in this condition.
