You're absolutely right that it needs to be much easier to acquire and use Bitcoins. I've already started working with a friend on a few concepts for UIs and workflows that'll be much better than the current system of run all over the internet looking for information then cross your fingers while websites take your money. While from an aesthetic point of view things would look cleaner if everything was nicely separated, I'm convinced the biggest hurdle we're facing right now is usability. Revamp the client, revamp the exchange.

On that note, do any of you have any suggestions outside of "more usuable?"

We have ideas ranging everywhere from trying to hide ugly addresses to an escrow using zero-knowledge proofs that never actually touches your money.
