Now that's just BS, sorry. Okay, the Pentium 3 is not 3 years old, it's more like 20 (soonish). I'd bet that there are quite a lot of machines out there that are >= 3 years old, running Windows 10. Or more appropriately, running a recent Linux distribution. Sure, at some point the hardware capabilities become a problem. But I just don't see that for a random operating system (Android in this case), after 2-3 years. The real problem seems the infrastructure - every vendor claims that it is a hellish effort to move all their useless crap and customizations, all their closed source blobs and magic fluff to a new AOSP base. And _there_ lies the core problem. If vendors would stop messing with random UI changes to 'be different', if manufacturers wouldn't hide their drivers, only THEN would your hardware argument come into play. If I technically _could_ upgrade my late HTC Hero to Android M I might find the performance lacking - although again: I fail to see why the basic operating system wouldn't work just fine, playing games or trying do watch HD videos on a tiny display notwithstanding.
