With the next major Windows Home Server revision, codenamed "Vail," Microsoft's home server solution is finally getting a major overhaul. The system is now based on the latest Windows Server version, Windows Server 2008 R2, which comes with a host of platform improvements that will directly benefit home server users. Like R2, Vail will be made available only in 64-bit form, where the current version is 32-bit code. And it will build on some of the more interesting home-based technologies that Microsoft has since introduced in Windows 7, providing what appears to be a very compelling solution for a market that, frankly, has pretty much ignored Windows Home Server thus far.
