So-called ergonomic keyboards hurt my wrists a great deal. I can type on them for 10-15 minutes. No problem with regular keyboards. Can and have typed on one of those for 16 hours straight with no issues.

But getting a keyboard again with mechanical switches really sped up my typing and made my fingers less tired.

Of course during the early 80s when I started typing heavily all keyboards came with mechanical switches. Gradually, manufacturers switched to cheaper, worse keyboards and mainly only people like me who had been using PCs since the early days noticed.

Now mechanical key switches in keyboards are making a resurgence, and that’s a really good thing.
