The team is working on this part time while we have our regular jobs as well. That being said, we are getting really close to have a stable platform that will form the testnet. I think people will be impressed by our work once the alpha is out.
I wouldn't go that far...
I mean from a normal's person/computer user POV, I don't think there will be much "on the outside" to be really impressed.
But as the saying goes, you don't judge the book by it's cover.
I think people will have a great time on the testnet. I think the average user will be pretty impressed with the client. I would go so far as to say that new users should wear diapers the first time they launch it.
