I'm honestly wondering if any current hardware will become retro in the future. Firstly, Windows 7 is very comparable to Windows 10 in it's core, so compatibility issues between the two are pretty much non-existent. As Microsoft said that they are never going to end support for Windows 10, which I highly doubt, then compatibility issues with current games and software should be no problem in the future. 😀
Secondly, the PC evolves way slower than it used to do in the 80s and 90s, so very 'old' hardware from 2006-2010 is still very capable today and components like the Core2Duo and the first generations of Core i3/i5/i7 are still widely being used by home users, businesses and schools and they aren't looking yet for a change. These systems are also very capable of running Windows 10, so people are probably not going to replace them any time in the near future. Compare this to the Pentium III, which was totally useless 12 years after it's release; times have changed! 😊
Thirdly, for me at least the current hardware will never feel the same to me as a Pentium III or older. 😜
