Yes. After struggling with every single type of Smart TV platform (Google TV, Apple TV, Amazon Fire TV). I settled for a Linux HTPC that I control with a Logitech K400. I finally found what I needed and I'm never going back to looking for crappy apps on some semi-empty store. Walled gardens are really sad.
You just need a remote with QWERTY and trackpad, and a few adjustments to the OS (e.g. 125% UI scaling works pretty well for me).
