10. Virtualization Hatfields & McCoys Continue Squabbling
Microsoft stepped up its campaign to convince the IT world that Windows Server and Hyper-V are far cheaper than VMware while offering comparable -- and in some cases better -- performance. This year, VMware finally started fighting back after taking the high road for several years.
Microsoft, after introducing the hilarious 1970s throwback character Tad last August, continued to use this creative marketing vehicle to hammer home its point. VMware, meanwhile, launched its "Get The Facts" website and jabbed at Microsoft for bragging about capabilities of products it hasn't yet released.
Wash, rinse, repeat. Expect to see more of this in the coming year when Windows Server 2012 deployments start blooming in the IT industry landscape.
