Coworker friend of mine has the (new) Droid Charge (4G/LTE) and we ran some speed comparisons against my Droid X (3G).
My 3G speeds are routinely around 1.5Mbps and my wifi speeds are usually around 11Mbps.
Running a side-by-side comparison at the office, pretty deep inside a building utilizing repeaters, he is seeing 11Mbps via LTE,. That is some serious speed on a little handheld device. I'm impressed. In a market where 4G specs haven't been defined yet, I was assuming he'd be seeing in the neighborhood of 2-3Mbps.
