    My big question would be: what's the lag?

    The last time I tried to use a cell network for internet access, the lag was horrid (300+ms) compared to real broadband. How is the lag on these systems? I'd rather have the responsive 450kbps connection than the unresponsive 1.5mbps connection.

      I've got an AT&T Tilt (HTC Tytan II) with HSDPA/3G/EDGE/GSM/etc and depending on where I am and what network, I get wildly different results. These is by using the bluetooth internet sharing with my MacbookPro in OSX or using USB internet sharing with my Ubuntu Linux Vaio:

      Location / ping to google.com / max download speed
      At my dad's house in NJ / ~400-800ms / ~65K/sec
      NJTransit Train in NJ / ~80-90ms / ~110/sec
      NJX Airport / ~40-50ms / ~120K/sec

    Maybe something already exists, but wouldn't it be cool if there was some kind of app that people could install on their laptops that would upload metrics to a central server and make it available to review?

    The app could tie into the 3G card and pull your approximate location, your carrier, and your average speed and upload it all to a server. As long as it doesn't also upload personal data, or your IP, etc, I can't foresee privacy issues (and it would be opt-in anyway).

    With enough people running an app like this, the data could come together quite nicely and allow people to view a map overlayed with the different networks and average performance.

    As an IT manager for a consulting business, 80% of my workforce is on the road 80% of the year. Broadband cards are absolutely critical to our success. We field test all over the nation and offer all three options. Our people have decided on 2 Verizon cards, 6 dozen Sprint cards and nobody has opted for the ATT card.

    Our consultants are regularly in NYC, Philly, Houston, Chicago, LA, San Francisco, Seattle, Vancouver and Dallas.

    If it helps anybody, Sprint is weak in New Jersey and parts of the Dallas area. Verizon picks up New Jersey nicely and this is where both of our Verizon cards are primarily deployed. Verizon and ATT are both not superior in Dallas so perhaps something else makes them all less than perfect.
