The Financial Times takes a look at Longhorn (subscription only, pah!).
The long-awaited new version of the Windows operating system is about to move out of the realm of the theoretical. Next week, Microsoft will hand out a limited early rendition of the software to help hardware developers design compatible equipment. ... In effect, Longhorn has been unbundled. Each of the three elements that were once touted as its key ingredients have been split off from the core system. One - a new file system known as WinFS... has been delayed. The other two elements Indigo... and Avalon... will be made available without Longhorn.
So what does that leave of the "core" Longhorn system?
I think we've still got to wait until ordinary developers and punters can get a look at the system before we can answer that one.
