I do, since I still enjoy using my classic amigas.
There's nothing wrong with that. What I dislike is breaking perfectly working classic HW by pointless overclocking (or attempts of overclocking). Working classic HW is getting rarer all the time. In my view it should be preserved, rather than trying to pimp it up the maximum until it fries.
If you want the ultimate performance (for instance in 3D), there are way better solutions for that these days (emulation, AROS, or other new amigoid systems).
