I also find entering numbers on a numpad to be much easier and feel more natural, probably because of growing up with calculators. They definitely have a place on modern keyboards.
Yeah, last year I finally dipped my toes in mechanical keyboarding and my 2 requirements were to have a numpad and some media keys for volume and play/pause. It was actually kinda a nightmare to find.
10-keyless keyboards are (kinda unfortunately IMO) popular with the custom keyboard crowd. I'm actually a little surprised that it's not available in an even smaller form-factor.
Really, this would have been an instant buy from me if it had a numpad. Kinda doesn't make sense that a retro themed keyboard wouldn't have it! I love everything about the design otherwise.
