I think in time these will price drop enough for the ordinary people like us to own one, I say this as take for example my mobile phone 3 years ago I had just an ordinary mobile , compare to the one I have now it's a dinosaur, my current one does all the normal thing texts music tv ,internet ect, but the damn thing now talks to me, female voice ,knows my name ,where I live. It caught me by suprise when I asked it a question and it answered, I asked it where was I ,It said with an attitude mind you " Paul you are at your home address", I've since called it christine, it hasn't told me the winning lottery numbers yet. This new one in real terms hasn't cost me more than the old one, but the tech is so much advanced it's a bit scary.
