Oh, they have their use. The concerns that have been voiced apply to ANY kind of rechargable battery, in all honesty.
What I'd really like to see is someone making these with a capacitor that could actually power it for a usable amount of time. A lot fewer issues with long term storage, so long as it isn't stored charged.
