What you guys think of the Logitech K750 Wireless Solar Keyboard for MAC WHITE/SILVER?
That's what I've moved away from, but mainly because I was running short of USB ports. It worked perfectly well while I used it, I could type quickly and accurately, and the solar power means you don't have to worry about batteries for it.
As I said, it has short-travel keys like the current Apple keyboard.
So an important question is why your partner doesn't like the Apple keyboard.
If it's the fact that their Bluetooth keyboard doesn't have a numeric keypad and their keyboard with keypad is wired, then yes the Logitech should suit them fine.
But if it's because they don't like short-travel keys then I don't think the Logitech is any improvement.
