I want to know the answer to the following question:
When was Mac's Xserve server discontinued?
All the background I'm provided with is that "Its current lineup comprises three desktops (the all-in-one iMac, entry-level Mac mini, and the Mac Pro tower graphics workstation), and four laptops (the MacBook, MacBook Air, MacBook Pro, and MacBook Pro with Retina display).". Is that enough to answer the question?
