Tom Yager's blog post makes the wrong assumption that applications should run exactly the same on a Java ME cell phone as they do on a desktop PC. Bzzzt! Wrong answer. Developers and content developers should be able to program and develop the same way on a cell phone and PC (like use the same NetBeans IDE) and use the same programming language, like Java technology. But, the same bits should not necessarily need to run on the two different types of devices.

Although in theory the Grand Unified Theory of apps running the same way on a phone as a PC as a TV, etc. has been around for years and sounds good on paper, in practice the reality is that the form factors (input devices, keyboards/keypads, screen res, etc.) are too different. For example, you do not run a Nintendo GameBoy DS game the same way as on the Nintendo Wii game console--two different paradigms, two different user experiences, therefore two different apps. The same bits should not run on the two different types of devices. A lot of people don't get that.

Here's a quote:

 It's thrilling to imagine rich, 
 responsive, attractive client 
 applications that run identically 
 on desktops, notebooks, and 
 mobile devices, as well as over 
 remote connections. Java promised 
 us that.
