No I doubt it but im not an expert. It was certainly worth reging for the small fee you will have paid. You have to speculate to accumulate.
If you try to develop it depends alot on the following....
There aren't many 'iPod Shuffle forums' about - they're mainly 'iPod forums' with an ipod shuffle section within the main ipod forum so it depends whether Sony continue with the Bean as a brand or just a one off product. If its a one off product, it will have a limited popularity and therefore the forum would die after a while. If its becomes a brand with the several different versions been released (not just different capacity sizes) e.g. The Bean, Bean Plus, and Mini Bean it will be worth developing it into a forum or selling.
The iPod brand is very strong though and Sony have found it just about impossible to break except in parts of the Asian market which they previously held and were leaders.
Hold on to it, try and find out what Sony plan to do with the Bean and go from there.
