If Bitcoin is going to take off, you've got to use it. I just talked to a customer service guy at Newegg. He said 'hardly anyone' pays with bitcoin. He said he's only dealt with two orders done in Bitcoin.
If you've got bitcoin, go spend some buying cool shit at Newegg or Overstock. The whole thing will fall apart if Merchants start seeing it as a waste of time.
Don't wait, buy some shit today! What are you - an idiot?
The usefulness of Bitcoin in retail transaction, is doubtful at best. I don't see any benefit in using Bitcoin in a domestic retail transaction, other than for some reason you need to be anonymous when buying a legal product.
The true power of Bitcoin is in a international cross-border transaction:
* US credit cards/banks bans online Casinos? no problem, we could fund gambling account using Bitcoin.
* darknet transactions
* open bazaar style markets
* international remittance
* true global commodity/stock market
Also the Bitcoin blockchain is useful for a variety of other applications.
