Was at a Costco yesterday and asked at the wireless kiosk if they had one. Answer: yes, a non-functioning demo.
It wasn't tethered, so I was able to hand-hold without the distortion of weight perception caused by a coiled cord.
Immediate impression: it's HUGE and somewhat heavy, compared to my Galaxy SIII. Liked the keyboard layout. I can see where people are concerned about the sliding keyboard and it's durability. I'm looking to see one actually usable next.
I still have an old BlackBerry 8700, ancient by today's standards, but the scroll wheel is next to useless now. But I greatly liked the keyboard ergonomics on it, and prefer it over the GSIII's virtual keyboard.
