Yet Another Exchange Killer?
jmertic writes "SuSE Linux now has the latest Exchange killer, but this time for Exchange Server. Openexchange Server is designed to be a drop in replacement for Exchange 5.5 users who don't want to pay the MS tax of going to Exchange 2000. They say it will be available mid November."
You are comparing, I think, a discounted web price for an Exchange upgrade with a list price for Suse. Suse will also discount, everybody does. Also, others have posted that Suse is charging per connected user, rather than the total number of users who ever connect (if I understand the other posts.) This will make a difference. Further, if you need to upgrade other software (MS OS, Office) and the only thing holding you up from going to Linux / OpenOffice is Exchange, then Suse's OpenExchange prices might not have to be far below the MS price.
However, if Suse really undercuts pricing, MS could always increase its discounts until SuSe's commercial offering goes away. This is a big advantage of true open source -- it can't be priced out of the market.
