From my experience, I'd agree with this. I got an Apple bluetooth keyboard from goodwill for $7 (retail ~$95) and used it with my hackintosh. Because it dropped out constantly, I figured I had installed antennas incorrectly, or that the ufl connectors were internally damaged, or… something. After upgrading to the newer (stupidly expensive) Magic Keyboard it works from anywhere in my house, as do my Power Beats Pro.
I don't know if the old (around 11 years old) keyboard had an implementation issue, or slight hardware damage, or what, but the new stuff seems rock solid.
