The perfect keyboard for me is the Logitech Wireless Solar K750, but it has 2 big flaws:
a) It discharges in around 3 days of heavy coding, and requires real sunlight, I had to leave the keyboard at the garden when the battery exhausted, and there are no alternate ways to charge it (the least I expected was a detachable USB cord).
b) Hardcoded limit of 40 pairings and no indication of that limit unless it won't pair anymore, I used to have two "Unifying receivers", one at home, one at the office, so I exhausted that limit relatively fast... It was frustrating and disappointing when I reached that limit...
