I love that the new client will be an entirely broswer based wallet. This will greatly reduce the barrier to entry.
At present, its very easy for me to have a bitcoin wallet at blockchain.org, or a dogecoin wallet at dogechain, or whatever. But having a Bitshares wallet was very difficult, required me to update the client, took a long time to sync the blockchain, and hogged my computer resources when I ran it.
This will be a MASSIVE upgrade to usability.
