I agree the first answer you got was a bit lame, but then again the question itself is a bit lame.
There are few G19 (-specific) applets because few people have developed them. It is similar to the answer for why stock prices go lower (more people selling than buying). That is likely because it is a relatively expensive niche keyboard. Developers of paid applications may have a vested interest in adding support. For free applet toys you'd need independent developers who own the keyboard and feel like developing and sharing applets for it.. Assuming your can live with G19 eye candy, AFAIK al lthe G15 applets should work on the G19 as well.
