A D-Pad... on a Spectrum. Wrong. Just wrong!
At the projected price, this must be aimed at nostalgics and collectors rather than the novelty seeker, but anyone who used an original Spectrum would have played with the keys for controls, maybe a robust Kempston stick for some action games - but D-Pads were a rarity, and often looked down on in their earliest incarnations.
Lots of games used more keys than this permits - and using keys let you configure your setup to physically match odd movements (like diagonals in most isometric games). Lots of people with Spectrums bought joysticks but went back to using the keys, it was the way to play!
I don't get it, nobody has done it right and made an actual functioning replica Spectrum (48k, rubber keys) with SD slot and USB/Atari controller port beneath.
And proper modern video output.
