Some sites return wireless keyboards even when specifically searching Bluetooth.

I like those! I may replace my main keyboard with one of those too.

I have the k480 which I like for typing and such, but for gaming I find it too small. It looks to be similar to your 380 but the 480 has a slot to hold a tablet or phone.

I do like hearing the 380 has a case though.

I was looking at the Logitech mx keys s, but it is $130. At that point I would probably go with a gaming keyboard.

The problem I have run into is the keyboards I am finding are either wireless with dongle, or very small TV keyboards.
