I've had an HTC8x, Lumia Icon and I'm currently on an HP Elite x3. The HTC was a great design...I absolutely loved the feel and look. Though small, it was a great starter into WP. The Icon.....ahhh...I loved that phone and still have it. The camera...mmmm, that camera with the Nokia app...that was sweet. The HP, large display, thin and svelte feel...premium (at least compared to most others). I have mixed feelings...if HP had the camera and Nokia app, it would hands down be the best thing ever to run the WP os....at least at it's release.
I know this post is older, but if you're skimming through and considering trying a WP phone, WP10 means the 8x is out. But if you like a decent size and great camera, Icon (Verizon) or 939 (AT&T) would be my suggestion. If you want size and premium feel, x3 is the one (as far as I know, only available on AT&T - gsm networks).
