Here is a nice summary of everything wrong with Bitcoins: http://brokenlibrarian.org/bitcoin/
Bitcoins were only ever intended as a conceptual thing (i.e. "This is how a virtual currency might work"). It was then adapted directly to a real implementation without much thought into it, and thus has a lot of serious flaws. I'm all for the idea of a virtual currency, but Bitcoins don't work well enough (it's debatable whether or not they work at all).
