Even without drivers though, Windows now usually has the basic drivers to allow a computer to be functional or will work with older drivers. My 2008 White Macbook runs Windows 10 very well with drivers made for Windows 7, and even without those drivers, most things worked anyway out of the box. You can install Windows 10 on almost any computer that meets the minimum specifications and have a mostly working machine.
While I appreciate there is work to do to keep compatibility, its not like Macs are cheap, they're expensive and high margin products so part of those margins should be going into long term compatibility. The way that Apple handled certain machines with 10.8 (namely not being bothered to write a 64 bit kext) was downright bad. My Machine was 3.5 years old and I paid $1800 for it - over 5 times more than the $350 Compaq Presario that was also bought a couple of months before it. The Presario runs Windows 10 with no fuss, where as the 2008 Macbook is stranded back on 10.7.
I can understand why handoff won't work on certain devices, as Apple created it based on Bluetooth 4.0 technology so obviously will not work on hardware without bluetooth 4.0, as there is no driver that Apple can magically write. However instances where Apple have arbitrarily cut off support for quite recent machines that cost A LOT to purchase, that is what annoys me. I believe machines should be made to last as long as they can as that is best for the environment and those who like holding onto machines for a long time. So with that in mind I do congratulate Apple on their good support of certain 2007 machines + certain 2008 Machines, and hope that they are supported for as long as possible, even if it means those machines miss out on features.
