wbmw, I see a clear thrend that PDA's are moving toward Java. This new J2ME is pretty new, I beleive it got to the Beta status just this year, but the acceptance rate is amazing. There are already many hundreds of small apps ready, and Motorola already started to ship it in cellphones for real customers. This is an absolute record of time-to-market for the last 5 years!
And you know why? I downloaded the toolkit few weeks ago (everything is free), clicked the "install" button as many times as it was required, launched it. And then it took me just 3 minutes to create a simple "Hello World" application, ready to download to any PDA (they all support J2ME now) and many existing cellphones. Without reading any documentation, because the toolkit can create a primitive app skeleton using the wizard. Amazing...
Can you imagine that the experienced developer can sit in the morning and by the evening create a simple game or application, ready to download to virtually any pocket device?
