Cao also complains that Apple won't support Windows on a Mac and that Boot Camp doesn't yet play well with Windows XP Service Pack 3, though Apple did release a Boot Camp patch to support SP3. Updates and reimaging are also more involved, since there are two OSes to deal with. "With Dell, you just yank out the drive, put it in the drive image machine, and you're done in 10 minutes." However, as with Citrix, many organizations address Apple's enterprise support shortcomings by shifting more of the management and repair burden to their Mac users.
There are also the usual complaints from IT departments about Apple's lack of product road maps, which makes planning just about impossible. To address that issue, Facebook simply keeps extra inventory around. "We accumulate lots of inventory right before Apple events because we know that's when they'll probably announce changes. This allows us to react and manage those changes until we're ready to move to a new platform." And the road map issue may not be that critical in reality: "Beyond three months, most technology road maps are lies anyway," says John Welch, senior systems engineer for the Zimmerman and Partners ad agency.
