Actually, what I most like is a flat keyboard with full keys and arrows and separate F keys and numeric keypad. Because most of what I'm doing is not entering long-form English literature, it's text and key combinations and numbers and arrows and symbols and mouse clicks and holding a phone and anything which requires the concentration of a weird entry system, or needs both hands in just the right places, or cuts out lots of keys to look stylish or take up less desk space or squash keys together to fit on a laptop, or change the alignment of keys weirdly, or assume everyone has prehensile thumbs which can take 90% of the key load on their own, or disregard years of muscle memory for a little temporary fashion, are ... worse.
