Your last statement of course takes us into the realm of sketchy wifi networks and the possibility of having one's devices and personal information compromised. Decided downside.

And everyone's responses take me to my last statement in the previous post, namely that you are at the mercy of your service provider which is more than willing to screw you over for the sake of a buck.

So my reluctance to engage with mobile devices because I can never know what it's going to cost me until after the fact is completely warranted. Until a deal comes along which lays out all the whys, whats and wherefors in a solidly comprehensive and understandable fashion (such as buying car or a lunch), I can see no way of my entering the world of mobile devices or other such stuff.

Thanks to all for the information. And, of course, MERRY CHRISTMAS to all!
