No ideas in particular, I just fondly remember for example the responsiveness of the Amiga - PCs still don't seem to be as solid clock-wise, and when you get into running apps in a browser it seems like the multiple layers of abstraction are really obvious. And that's just on a desktop - Android is even worse! A pretty horrible laggy UI, and once you get into the horrific disaster that is Android development the underlying cause kind of reveals itself. Imagine the tightness of a mobile OS running close to the metal and how responsive that device could feel. You used to be able to switch on a device and the OS would immediately be there - indeed embedded devices are often still like this. Perhaps I'm just being too nostalgic though, and I realise Amiga OS was missing essential things like memory protection etc. that we now take for granted.
