I have the MBR1000 ordered and it should be here tomorrow. I can get either AT&T or Verizon for about the same discount (24 or 22 percent) and the same price for the USB dongle. Has anyone here used both that can give a good idea of coverage while on the road.

I have had Verizon up until last June for cell service. Switched to AT&T for the iPhone 4, and have not had any real issues. Do the USB devices pretty much mirror the phones for coverage?

It appears from the advertising hype, that Verizon may have a jump on AT&T for the 4g stuff, but advertising is hardly reliable.
