Have two Al usb keyboards, a iMacG3 plastic one , and a MacClassic ADB.

Mice…. Many Usual teardrop ADB shape : 2 beiges, 2 black, 1 grey. 1 squared shape ADB for the Classic.

1 wired Mighty mouse, 1 Bluetooth Mighty Mouse, 1 MacPro black/transparent, 2 usb iMacG3 round .

1 ADB non-Apple two-buttons mouse, can't remember the brand. And 1 ADB two-buttons NeXT , the strange shape one, work great on old Mac but I wish the squarish shape one was ADB...

And maybe 6 or 5 usb mice of various brands.

I collect Apple laptops, so don't know if I'm allowed to speak here  but seldom use trackpads...
