Whats this mean for EVDO users? It means you can use an aircard/modem in your laptop and, using the built in wifi adapter you already have ... you become a hotspot for other wifi enabled devices - no router needed. And full security.
How? Windows 7 had the capability to do this, but never offered the software in the final product.
Well, a company has stepped up and made it available.
I've been running this for over 2 months, and it works great. Get the program here: http://www.connectify.me/
So hmm ... why pay $$$ for a MiFi device? You now have the same capability with your own laptop.
