I bought some... hardly any, USD 50 worth, a couple of days ago.
Before buying, I was getting tired of sitting on the sideline waiting for Bitcoin to fall so I could get in at a more affordable level (like say 1btc=USD200), so I bought when it was at about USD836 on Bitstamp.
Now I've actually got some, even though its a really small amount, my perception has changed - I'm now certain its going to crash to a more realistic level, and probably sooner rather than later.
