1480407 story IBM Challenges Microsoft With an Ad Campaign 210 Posted by Zonk on Friday March 31, 2006 @06:04PM from the draw-sabers-and-duel dept. Rytis writes "IBM is about to spend $300 Million dollars on a campaign to win customers and to convert them from Microsoft Exchange to Lotus Notes and Domino under Linux. IBM is also said to offer resellers a bounty of $20,000 for switching customers to its Linux-based e-mail programs from Microsoft server software. It seems that the concurrence Microsoft Corp. is facing is getting tighter and tighter. The Penguin gets more and more support from the two biggest rivals that Microsoft have ever had."
