Well I turned on hotspot for a month to play with it. Here is a speed test on my Acer Iconia A200 Tablet WiFi tethered to the Rezound with good 4G coverage.
My EnGenius EUB362 usb WIFI Adapter is pretty slow on my desk top through the Rezound. Will have to try laptop. Old XP LapTop runs slow also. Guess I need a new g adapter.
OK some more to report. Both gmail and the market work correctly on my Acer Iconia A200 VZW mobile hotpot on my Rezound. With Bluetooth FoxFi/PDANET Tablet they did not work. I could surf the net OK however. So until some thing changes, I guess I will give it a try.
