Re: Yes and while your at it...
The old version of windows is shit because it's ancient and out of step with computing in the 21st century. The new version of windows isn't so shit when you look at how many shitty things they're trying to fix. But I digress.
You wrote "In the meantime, what is so differnet about an emailed doc printed out and a fax?" - well, the difference is that an emailed doc DOES NOT HAVE TO BE PRINTED!! What is this fascination with having to print everything?
And you wrote "Don't pagers have guaranteed delivery?" and the answer is NO. For guaranteed delivery you'd need something like, um, a mobile phone, which can actually send delivery receipts with texts and also can run several apps that do the same such as whatsapp, google hangouts etc.
