Logitech k480. I carry it everywhere. Has a three way switch, iPhone, iPad and Mac. Only problem is it interferes with headphones/wifi somehow. Mac cries piteously when the k480 connects.
Other pluses: rearrangeable keys (dvorak), runs on AAA batteries.
The legends eventually fail, and the keys take a shine.
I wouldn't recommend either though, for both, the keys are not nice to type on if you don’t press perfectly downward, if you have any angle other than vertical, the keys occasionally bind a little. This is amplified on the 480 with longer key travel. They’re different types of key mechanisms on both but suffer the same problem.
If you have any kind of case, the 480 stand slot can be harder to use.
Logitech k480? Oh my god and it even has round keys!
