Marketing ploy. He is Microsoft. No way he believes it's "less good". A lot of people use it. like it, and love it. I was one of those people. "We know it's less good" "Now go ut and buy a copy of our newest operating system"
I personally believe that last sentence should read "Now go ut and buy a copy of our new and marginally operating system that is based on our less good operating system but expanded and hopefully improved and if there are issues we hope you don't notice them too quickly He's not being honest. He's just throwing out a weak sales pitch."
