Vista development, which started with the Windows Server 2003 core, which in turn started with the Windows XP SP2 core, is in the same league with Microsoft's Windows 95 effort, and not far behind the gargantuan Windows NT undertaking. Whether you love Windows or not, whether you believe in Microsoft's ability to innovate or not, you can't fault the software giant's R&D efforts with Windows.

The question is, what does all that work mean to you and to businesses the world over? What are the benefits? What are the downsides?
