so they ARE double shots right? what makes em so special?
WIth 70+ posts already, I thought you would already know ...
On double-shot keys the legends don't wear out, because the lettering well.. it is as thick as the key itself. It is high quality.
Unfortunately, your keycaps don't look like they were made by Cherry corp. Cherry's own double-shot keycaps are the highest-quality Cherry-compatible key caps that were ever made. The plastic is the hardest and the walls are quite thick. Many people feel that these key caps just feel better than the others .. but then, they are also quite low and therefore less wobbly.
Windows got support for USB in a service pack to Windows 95 in 1996 or 1997 if I am not mistaken. I got myself a Windows PC in early '97 which supported USB 1.1 out of the box.
I don't know when Cherry started making keyboards with the Windows keys.
