A 10m HDMI cable connecting your TV to your laptop on the sofa is not hassle-free---that cable is the hassle. I'm doing the same things, and I find it a hassle but haven't yet been willing to cough up the $100 for an Apple TV + AirPlay wireless solution. Unfortunately, their dongle costs nearly as much.
Is it though? I mean, it just hangs over the arm of the sofa and I plug it in when needed. Plus HDMI is one of the few ports on my MBP I don't need an adapter for.
I get that cable free would be awesome but as I understand it we need significant advances in inductive charging to make that happen.
