I use 6 computers, two at work (MacBook and iMac) and three at the house:
A custom-made Linux Desktop with Ubuntu Studio,
A HP Pavillion Laptop: (Dual boot Windows - Ubuntu 12.04)
An iPad Mini
Not counting one old iPod Touch, and one Android phone,
I wish we could replace Facebook with independant networks, but that's not going to happen,
I used to be a big Apple Fan, not so much since IOS. Apple is getting kind of creepy now with the whole ecosystem they are trying to wrap us into.
I wish every school would use and teach free software, show the kids how it works before they tackle anything else, spread critical thinking. And that's not going to happen either, at least not where I come from...
