It will have enough new features and bug fixes along with performancegains that users will want to move to it, and in order to move to it newoperating systems will have to be sold by the truckload. Microsoft is and has always been aboutLEVERAGE. To run the newest THING you need the new OTHERTHING, which meansthe new OTHERSTUFF.....etc...etc...etc...AlexScoble:Firmsthat are already on decent hardware and have Exchange 2003 will find thishard to swallow. ...At any rate, this will probably pushcompanies that are looking to upgrade their collaboration infrastructureto look at other packages such as Scalix or Open Xchange.orperhaps Lotus Domino, Alex?FerrisResearch:64-bitsupport makes great sense and is good for everyone.Youcan read my comments on Ferris's site for why I don't agree with that. (Also picked up by TomDuff).Some other responses are linked in the previousthread.  Net net -- I'm gladNotes/Domino still stands for investment protection, not rip-and-replace.
