For most enterprise customers that have their own displays, most of those displays are connected to PC laptops of varying capability that the employee can take with them and easily work remotely if they’d like. Another large chunk are connected to Mac laptops of varying capability. Very few of enterprise machines are desktops.You don’t think enterprise customers that have their own displays wouldn’t utilize this category of Mac, that would be a odd thought. This mentality of iMacs and laptops are adequate for all needs is contrary to business usage. It started back in 2005 with the PowerMac G5 that was renamed Mac Pro. Apple through the following years constrain us to accepting only their limited product lines over what business typically deploy in offices. I do agree that the latest MBP and iMac are quite useful for a lot of purposes, but neither suits the enterprise like a good desktop.
COULD enterprise customers utilize it? Yes. But, Apple’s sales (as provided by analysts as Apple doesn’t report breakdowns by product) show that desktop headless systems make up a sliver of Apple’s sales. Are there a few enterprise customers buying thousands of headless Macs for their server rooms or other purposes? Surely. But, a few thousand Macs in server rooms are still dwarfed by the millions of just MacBook Air’s in use.
Apple doesn’t focus a lot on desktops outside of iMacs because the numbers of those systems sold are tiny in comparison to everything else Apple sells. It’s not a “mentality” that iMacs and laptops are adequate for all needs, it’s a fact that, of the systems that Apple sells (that’s across consumers, education, and enterprise), over 80% are mobile systems.
