Still had one on my Amazon wishlist, but couldn't justify the expense because apps have been good enough for me so far.
@alleycat @wonderofscience oh, so nice! Could you share the Amazon link, please? I searched on the US store, couldn’t find any. I would happily return that one I linked (which will deliver today), and order this one instead!
I know apps are, perhaps, better, and extensible. I love that mechanical sound, and physical feeling, though. 🙈
I'm in Germany, so a link is probably of no use.
