I agree. I have a 2011 mini server with integrated Intel 3000 graphics and have never had a problem with anything. I understand that if someone is a professional doing large file photo or video editing they would want a discrete graphics card, but for the average user, the Intel 3000 and 4000 graphics are so far above what integrated graphics used to be (and people are projecting bad experiences from years ago onto today's tech).
As for Hackintosh, that's how I got into Macs. Yes, you can build a custom Hackintosh, but it's not a Mac. For one, they have no resale value, period. They have issues, and if Apple is dropping dedicated desktop graphics cards, good luck updating OS X on your Hackintosh in the future. That's the biggest problem with Hackintoshes, compatibility and updates. Every update can break the OS, meaning hours or days spent trying to regain what you just had. I finally decided I just wanted a real Mac and stopped dealing with the headaches of a Hackintosh.
