Huge reason for me not to go Verizon. That mobile hotspot thing will be great until it stops a blog post in the middle of its tracks to receive a text message. Also I realize that AT&T doesn’t have that mobile hotspot feature, but do you honestly think that come the next version of the iPhone they won’t have it?
Also the existing iPhone cases may not fit the Verizon iPhone (WTF is that?).
