Previously we were giving our old laptops to friends with kids. Now our kids use our old Macbook air to learn to type and other learning programs.
My old MBP runs our 2010 "smart" TV via HDMI. It's not perfect because we have to get up to change the movie or skip an ad, but it works. And man, that thing still heats up like a mofo even when only running a browser, jeez.
I used something like this with my computer and xbmc back in the day. I had a wireless keyboard/mouse combo for situations where the remote control was less helpful, but this covered 99% of the requirements quite nicely.
