I think I spotted a Treo 650 today. I can't be positive -- since I have a 180 and not a 300 -- but it appeared to be the new model. It had the pointy earpiece so I think it was a 650. This was on the plane from Chicago to LA this afternoon and it appeared to have a Sprint logo on it. I didn't get a chance to ask the owner about it since we were deplaning and he was on the phone, but I presume he was a beta tester.
