"Today at CES, I met with Steven Sinofsky, Windows 7 development chief, and asked about the unprecedented free-for-all Windows 7 Beta available tomorrow to anyone who's interested. Is this the "free upgrade" people wanted?
When I asked him if it was an unprecedented move, passing out the whole operating system to anyone and everyone who wants it, he said that technology limited previous rollouts. Windows 95's beta test group was 600,000 strong, downloaded mostly from dial-up via FTP sites. He says he even remembers putting out DOS in 1992, and getting 50,000 downloads-within a day. This, though, the combination of the TechNet and MSDN subscriber downloads with the open beta for all, will dwarf those previous OS beta runs. So I asked the obvious question: Are people going to dump Vista for this, wholesale?"
