(i) What I love about the keyboard:
1. The build is great. Rigid, heavy, firm, and stable. I have two full size Das Keyboards as well, but they never stay on the desk as firmly as this Filco TKL does.
2. The form factor is prefect. It is simple, classic, has no extra edges (as e.g. some Cherry keyboards do) and fits perfectly on my desk between my other lots of stuff.
3. The Bluetooth works great, and I can just occasionally plug the usb cable in or out, just to have some variety. I had a problem with freezing of the keyboard on a letter once in a while, but I realised that it is a problem with the intel Bluetooth driver in interaction with power settings. Now the problem is solved.
4. The cherry MX Blue switches sound. No rivals. I type a lot and write a lot, and this is the heaven of a writer.
(ii) What I like about the keyboard:
1. The materiality of the frame. It is kind of a rugged plastic, and feels comfortable. Its not shiny or smooth therefore it doesnt show you the dust or finger prints.
2. The rubber pads under the keyboard. There are nice rubber pads under the keyboard, both in the flat position and under the legsstands. Although I dont use the legs, but still a must have feature.
3. The customising pins under the keyboard, which I havent used yet.
4. The multi-device option. I have already connected it to my laptop, ipad and iphone. Switching and pairing the Bluetooth was an enigma at the beginning, but finding the tiny English part of the manual on page 20 by help of the KeyboardCo customer service helped a lot.
(iii) What I dont like about the keyboard:
1. Perhaps the only thing is the material of the keycaps. I think they are ABS (not sure). But the surface is too smooth and I dont like the touch. I am therefore replacing the key caps with Das Keyboard Caps which are more sandy. I am also using orings under the keys to reduce the base vibration effect. But that is just a matter of taste I guess.
