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.
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.
Pretty cool looking, but I'd need to know how sturdy it felt and what the keys were like before buying it. As a novelty alone I don't think it is worth it, but if it is also a good keyboard then I might even get one.
If they want to make a retro-styled keyboard they should make one without the "Windows" and "Menu" keys so that you can play Commander Keen and Duke Nukum the way they were meant to be played.
