Let's make this realistic.

I'd like to buy one of the new AM3+ Asus Sabertooth mainboards, along with a befitting black edition Phenom and 1833 CL7 RAM with at least 5 year warranty, preferably from the same merchant, shipped to Germany speedily at competitive prices.

Can Bitcoin do that right now? I doubt it. There are a few dealers who can fulfill my request, but none accepts BTC! I would have to use some middle man magic, and nobody feels like doing that.

That's the thing. It's like saying Android has a good security model -- it's all good in theory, but the reality is: there's still a lot to do.
