Anecdotally, I did. I'm a complete bitcoin noob, but owned 5 coins in CB since it was super easy to do. Read the Ask HN from last week when the first email came out from Coinbase. Downloaded Bitcoin-core for OS X, went to Receive and got a QR code, pointed the Coinbase App at my screen and sent the funds (tested it first with a few dollars worth). Then did the big bucks. Note: the most painful part was downloading the entire block chain. Took many many hours. Copied the wallet.dat to a few other hosts and I'm done. Hopefully this will be helpful to anyone else on the fence.
