It does have some benefits, but it's no "killer app".
Find some place where bitcoin "fits" and build a community there. Perhaps the anonymous networks, perhaps somewhere else. I'm afraid bitcoin will never take off, just existing as a fun thing for the libertarians and anarchists. :-)
I would love to be wrong though.
You don't get it yet, it's a store of value, that's where it fits. As it's such a good way to store and transact value, it's not going to go away until the internet does. How easy it is to buy a loaf of bread with it at this point is of no more importance then how easy it is to buy a loaf of bread with lumps of silver.
The secondary growth potential is enormous, I'm reading this forum and seeing the creation of whole new service industries, it's a self-reinforcing feedback loop. For me bitcoins have already arrived as a valued commodity that is actively traded and actively hoarded. No one's giving more than 0.05 of them away for free. Not being able to spend them directly is entirely irrelevant.
Think of it like classic cars, there' a market for that, there are people who think of classic cars, or classic shoes, or 'art' as safe place to put their money. No one cares if they can't always swap their classic car directly for something else and have to use dollars or pounds instead.
Difference here is that bitcoins are easy to change hands directly, and you can spend their value fractionally, for things smaller than the cost of a full classic car. Right now the bitcoin economy is probably the size of about a hundred chevrolets. lol.
