The EVO phone can also serve as a mi-fi router for up to 8 computers, or if your at a desktop, can be hooked up to your PC using the mini-usb port. As a trader, I would think something like this would be invaluable as it gives you access if outside or if your primary service were to go down. Was thinking of getting the regular mifi device until I saw this one coming out and think it is the much better buy.
Plus your iPhone can access the Sprint data network using its wifi.
I guess I will wait for this. The HD stream to TV is pretty sweet, if I am understanding this correctly, you could load your trading software and use a tv as a monitor when you are on the road. Combine that with the "monitor glasses" and a rubber keyboard and I can be that guy on the beach who is really annoying.
