Change of plans on my new work phone. My son has an S4 and I walked around with it in my pocket for a while. I liked it. It's really only slightly bigger than my HTC 8X. The edges of the S4 are slightly thicker than the 8X. I really like the form factor of the 8X, it seems perfect for me - it's just too bad the phone itself sucks so hard. I also went to Fry's and looked at the Droid Mini, Moto X, S4 and S4 Mini.
I think the Samsungs win - they just felt the best in my hand. I probably should get the S4 Mini, but the S4 has better specs and seems like the better deal - and it does fit in my pocket...
