Bitcoin is all good and dandy the only issue is that you cannot use it as means of transfer on a personal, physical, day-to-day level efficiently, phones batteries do not last that long these days and phones are relatively expensive, e.g. you should "own" 400$ worth of assets to be able to spend 100$.

What seems to be most beneficial to the community at this stage is if a company would crowd fund a device with a modern, stylish and cheap design which is capable of transferring coins from Bob to Alice nearly instantly with a low chance of a double spent transaction.

The design would include dual processors, one almost always in sleep mode unless hashing is needed and the other one is there solely for the purpose to wake the first one up should the event fire, the battery would last say 30 days without recharging. All of this is possible with modern technology except for the limitations imposed by Bitcoin/the state inherently, such as police not willing to arrest the owners of fraudulent "miner" points which are likely to be needed to synchronize all the devices that are near.

I am curious as to what would be the best scheme for all of this to work together effectively?
