My daughter has an X220 that she used to play Minecraft on,
but it doesn't get much use since Minecraft PE added most of the features she liked.
Other Home Network-Connected Devices
-------------------
I brought in a Google OnHub wireless router in an effort to demystify
the router for my family. It worked.
We also got a couple of Nest thermostats to test the claim that they
pay for themselves. This would probably be true if we had air
conditioning in the house, but we haven't saved enough on heating yet.
But it is handy that they turn the heat off when you leave the house,
and several times we have twiddled the temperature while out of town,
usually to pre-heat the house when we're arriving late on a cold night.
We have a Brother laser printer that connects wirelessly and speakes Google Cloud Print.
I can no longer print natively from Linux,
but it turns out I don't really want to print things from Linux much anymore.
Google Cloud Print lets you submit a PDF through a web form,
so it's not a big problem.
We also have a Chromecast that's mostly used for Netflix,
and a hacked Wii with a few movies on a connect USB hard drive.
Our television is *not* a "smart TV" and I really hope we can avoid ever having to bring such a thing in to the house, they seem slow and buggy, not to mention the ads.
Our car is an all-electric Tesla Model S, which is offset by a small
solar array on the roof. The car has an ext4-formatted USB flash
drive plugged in, with our entire music collection.
