J2ME is quite WORA

From a prototype working in WTK to device in no time! Well, of course attention has to be paid... and conscious decisions to use (or, rather, not use) certain API levels. Overall, enjoyable experience I could recommend to anyone. After all, all software to get from one's idea to an app deployable to device is FREE. Netbeans 5 with Mobility Pack was all I needed to develop, and Motorola MidWay + USB cable + drivers were used to upload app to my phone. Although, frankly, I would have preferred using OTA as my USB cable has really bad contact, connection is unreliable. This app by no means is impressive, but if it is of utility, that justifies its existence and (as little as it looks to take) effort.
