I tried the MS Skydrive, and the free cloud space I get w/Comcast. Actually I guess I do use it for my Kindle Fire, but only for a few non-personal things like a book or two and one or two games. The other two are painstakingly slow to upload to, and Skydrive is much more awkward to use than it should be. I have a very fast download speed, but uploads are simply too slow. Then there are security and reliability considerations. When I can buy a 2 TB hard drive for just over $100, it's not at all obvious why anyone would want to use this abomination. As for backup, I can do that to an external hard drive, and put a copy on a flash drive locked up in my car (which has a security system). I have on occasion put some data in my safe deposit box, but that's really overkill for me.
GoPro, Pixpro, or Ricoh?
You can spend hundreds or even thousands of dollars on a 360-degree camera. We tested three of them to find out what kind of quality and ease of use you can expect at each price point.
