Yes.. and may be worth some money to the right person...
... at the moment the only two advantages that bottle dynamos have over hub dynamos is that they are cheaper and easier to replace.
All this will change in ten years time, due to economies of scale, when bicycle makers can't sell a bicycle without a hub dynamo...
...already we're seeing expedition bicycles produced with hub dynamos so the rider can charge their phone, their camera and even their laptop (so they can update their on line twitter feed and blog site)...
...racing cyclists who use electronic gear shifting will be the next customers in line for hub dynamos, simply due to the fear of there gear shifting batteries losing power mid race..
...and after that are general commuters who expect their bicycle to have the same 'contectivity' as their cars, and expect to charge and use their electronic devices while cycling...(like using an app on your mobile phone to follow a route that you have planned, without the fear of getting lost)
...once laced into a wheel hub dynamos are easier to fit than bottle dynamos, so they'll be some savings on the cost of the dynamo hub itself, but that cost would also be driven down by the bike builders and because dynamo hubs will be everywhere.. you'll be able to get them off the shelf, should your old one fail...
..as a result, market demand for bottle dynamos will drop and everyone will stop making them, leaving a potential market for second hand bottle dynamos...
Eventually the number of tyres on sale with dynamo tracks will cease as tyre makers up date their moulds..
...even worse there may even be a reduction in the quality and range of 'non dynamo front hubs'...
However, as the number of bicycles using dynamo hubs increase... it becomes harder to argue against the introduction of 'day time running lights' for cyclists.. and by the eleventh year 'day time running lights' become uk law...
