Sure, lots of people run their business from one and almost everything these days is targeted to the users of them. But personally I have no time for them. What I can't do on my PC is not needed and what I can do on my PC is many times more secure, ie: activity and messages are stored on my servers and a PC cannot fall out of my pocket for the next passer by to collect. Also, usage is much more economical. But then I don't use a land phone either. In fact I do no business by phone at all. Then when I walk away from my PC I have complete privacy.
Er, what was that you said? Sorry but I can't scroll back on my phone. Or, can you hold while I can get something to eat? Then we can both be chomping while we discuss things. Or, yes it's obvious that you do indeed speak very good english, but I cannot understand your f****** accent!
