Love it. Most in this group don't even know a world without MS windows. Most people never had a personal computer in their home till about 10 years ago.
I am pleasantly shocked with "surface", but have been waiting for a new technology to come out. Since windows came out, there has been great improvements in it and much new technology for using it. But it's still "windows" on your monitor with a keyboard and mouse. "Surface" is overdue.
Once on the market, it will be very expensive at first, but after a few years, everyone will have them and the price will drop drastically.
