That's a tough question to answer right now, but there are signs that you'll want a pretty beefy computer when you make the upgrade. Microsoft Watch gives us a few
tibits of information...
- It's currently scheduled for end of 2006 (but don't be surprised if the date slips.)
- Last year some sources indicated unofficially that the average PC with Longhorn was recommended to have:
-- Dual core 4-6 GHz CPU
-- At least 2gig RAM
-- A graphics processor 3x as fast as those currently available
and more!
- At WinHEC this year, a Microsoft group product manager said "most existing mainstream 32- and 64-bit CPUs from mainstream manufacturers should run Longhorn." (But that may not mean it would be a pleasant experience!)
- Set in stone are requirements for at least 512Meg RAM and "support for the new Longhorn Display Driver Model (LDDM) in order to handle the operating system's new graphical features."
- A Microsoft developer "did advise mobile PC makers to consider supporting 802.XX wireless; General Packet Radio Service (GPRS); Bluetooth; the various Tablet PC input technologies (including speech and touch, in addition to digital ink); ClearType, the hybrid flash/disk technology; and Longhorn's forthcoming Secure Startup capability, among other features."
So bottom line, I'd say you better plan on running Longhorn on a computer you don't own right now. But that's okay because your current PC will probably be pretty out-of-date by the Longhorn is available anyway!
