I am currently at Starbucks surfing away as I regularly do and thought I would try out my new Verizon Nationwide Access to see how they compare in connection speeds.  This is what I found out.

Verizon Nationwide Access Speed Test Results

I used a site called FreeSpeedTest.com and it seemed to indicate that the T-Mobile hotspot is over 3 times faster than Verizon's Nationwide access.  I am actually just borrowing the Verizon Card from a friend who no longer needs it and wants to know if I want to take over his account.  So, I guess that I basically have to decide if having Nationwide Access at a relatively slow speed (relative to T-Mobile, that is) with nationwide access is better than high speed at limited Nationwide Access.  I use the term "limited Nationwide Access" because Starbucks and Borders are all over the place, so I usually don't have to search too far.  It is still not the same as being able to just connect from anywhere, but not bad.
