I still have a 500 and a 1200, but I don't dare to switch them on because of what I was told about old condensator components which could melt after so many years and ruin the motherboard.
In fact, I'd love to buy a brand new 1200 today and reconfigure it from start. But not easy to find such hardware in France (i take all suggestions !
So today I use exclusively WinUAE. The software is awesome, but it doesn't have the smell of a real 1200, but it is better than nothing.
