I've just been using the onscreen keyboard & PS4 controller and while it works, it takes me 8.7 minutes to respond "OK" when someone messages me.

So I've been looking around in the brick stores & I haven't seen a PS4 keyboard for sale.
Hmmmmm, this sux. Everyone else in game can send me entire paragraphs in 1.7 seconds, but these fleshy gnarled extremities I've got barely let me tap out "OK" in 27.8 minutes.
Bur I'm not going to accept this. How is it possible? Let's use some detective skills...... and the internet.
Google PS4 keyboard. Hmmmmm, what's this? Oh well now this is cool. It fits right into the controller. This must be how everyone is typing in game.
So I look for the Sony brand of it, and it turns out that Sony does not make those types of keyboard peripherals. Sony says just plug your usb or Bluetooth keyboard in and go. So I grab my pc keyboard, plug it in and TADA it works.
The problem is that it is corded and it's a big honking Logitech G15 keyboard on little table next to my chair.
So I'm asking for some advice from the PS4 community on what you use as a keyboard.
By the way, these are the keyboard peripherals for the PS4 controller that I'm talking about.
