Admittedly there's not a lot of places where this is necessary at the moment due to a recent trend in opening Wi-Fi hotspots, but if you travel a lot, it's *very* useful in larger airports where paid Wi-Fi is still the rule of the day. Yes, I don't connect on VZW Wi-Fi as often as I do AT&T Wi-Fi (access I have due to my mobile phone), but every time I do connect with Verizon, I save something like $10.
Which makes it even more annoying that I still can't install it on my new Win7 machines. I really need to suck it up and start calling tech support -- it just sounds like such a painful process...
