Any new additional target platform would be great, specially such emerging and supported by larger company that know what is doing so it shouldn't end like with HP. Of course that OS probably changed a lot from times that GLB could compile for it, so it would require some work to get it on track again. And as you wrote such niche markets can be great place to publish/sell games as there is just a small variety of games on them. There is also another thing, that would be good advertising for GLBasic if it could make apps for new WebOS, as one of only few tools.
There are also some others possible platforms, but it's different story.
