I'm running out of space on my laptop and would like to move some old files to the cloud. I also have old files on a couple of USB sticks and external HDs that I'm a bit paranoid about losing so I'd like to move this data to the cloud as well. What's a good solution for that type of problem? Since some of that data is sensitive, I would require a solution that supports encryption.

Why can't I install stock Android on my phone just like I can install Linux on pretty much any PC? Is there a fundamental difference with phone hardware which makes this especially difficult?
