Well, a while back, whistler was supposed to be "Windows 2002" and Blackcomb "Windows 2003". But maybe the schedule got pushed off, but maybe not. The Blackcomb development is well under way already.
And .NET is the Microsoft new strategy to "rent" their software, not sale them. In the future, you will decide what you you make of your computer and lease software from Microsft according to what you need: specific features of Windows, with some specific featrus of Word, Excel, etc. You'll mot likely pay a monthly subscription. That's the plan. Also, .NET includes a proprietory standard based on a new programming language called C# (read C sharp). The engine is called Hailstorm and will allow you to access your data and share your data from and to any device: digital cameras, scanners, removable disks, online spaces, PDA, cellular phones, digital picture frames, even your car your ecommerce web site, and the list goes on. Of course the makers of those devices will have to be .NET compliant. And therefore the whole digital world will then on revolve around Microsoft. The DOJ haven't seen anything yet regarding antitrust... But that's not the end of it. All your information will eventually be stored on Microsoft's servers, including your calendar, you credit card information, your business contacts, etc. You will be able to give permission, for example, to an online traveling agency to automatically check your agenda for the best suitable time and automatically bill your credit card.
Anyway. All this is supposed to be revolutionary, but to me it sounds like the begining of the dark ages...
