I thought this was an interesting article:
How realisitic is it for an independent freelance Java developer to earn a living creating games? What game platforms have the most potential? PCs, PDAs, Cell Phones, or Game consoles? I own a Sharp Zaurus and I’m impressed with it’s Java integration but is there a market? What impactl will the court ruling putting Java in Windows have? We’ll soon have Java on all new OS X and Windows platforms. Thanks.

After witnessing what logos, tunes and such did for SMS/GSM service business, I am a firm believer in the Java games that can be downloaded to mobile phones. The deployment of Java games for them is so simple anyone can do them.
See www.garagegames.com for some nice ideas about future of “indie” game development! (EDIT: Oh there was a link in the article you referred to…

In another world maybe - of you need a big bunch of luck and get to know the really right person at the right time. Then, everything is possible.
