A Good Reason To Back Up Your Pooter.
A few days ago something sent my computer into a terminal bluescreen. I uninstalled and installed stuff and I think I gave it a migraine. Anyway, the upshot was I had to have it go through a recovery to Factory settings and all data was wiped. Luckily I had everything backed up on a USB widget so I only lost a couple of bits that hadn't been backed up. It only takes a few pounds/dollars(for the widget) and a little time, so if you don't do it already, please make sure you do!
