What's keeping us from trusting this application to store our primary wallet?  There are some warnings on the project that this is Alpha and to use testnet.  I don't see what the problem is, if the underlying framework is actually mainline (Jeff Garzik) bitcoin source and this is mostly a wrapper.  How is the wallet in any danger?  I want to get my BTC off my Windows box and onto my Linux box using this as the main GUI.
