Oh, I definitely think 10x has its uses. I always am in the process of reevaluating my opinion of some of those out there. For example, Cabelas screwed up my order. Remember my saying I was ordering an 8x42 Alpha Extreme? Well, I received email verification of shipment...they sent the 10x42s. I will give them a fair shake but the smaller exit pupil and smaller true field of view usually turn me off fairly quickly.
Still...I love it when the UPS truck rolls up to my front door.
