This keyboard works great for switching between computers and my phone. The only drawback that I can find is that it is NOT a full AT keyboard. It is missing the Print Screen, Scroll Lock, and Pause/Break keys. Most people never use those keys, but as an IT professional, I use them frequently. And that is disappointing. I mean what would it take Logitech to have implemented the whole AT keyboard standard? The other annoying thing for me is that by default the F keys are not programmed to be the F keys, they have special functions to do with switching between devices and controlling other things. Again, most people don't use the F keys much, but as an IT professional, I use the all the time, and it can be frustrating. There are setting to put the F keys back, but then it is less convenient to switch between devices. So a not so great trade off is all you're left with, when all it would have take was 3 extra buttons. On a $50 keyboard, that's unexpected and kinda unacceptable.
