Graze Snack Dine.I've never seen that sort of problem. I find most things I want to do I can do easily with it, and for watching TV on the big screen I use a chrome cast. It seems a bit odd having a mobile device and then keeping it in the corner of a room with a cable.
I do a lot of development stuff, so as soon as I'm doing more serious computing then I move to a laptop. I see them as different tools for different tasks.
Graze on phones & tablets, snack on entry level desktop/laptop, dine on power PCs.
