Cloud computing really takes the strain off important documents, pictures, and info if you keep up with it.
I almost lost all our pictures and videos of China from when we got our daughter thanks to a cheap ass netbook.
Luckily, my wife had a single armored thumb drive with a backup on it.
Never Again!
I have a Western Digital, My Worldbook II. Kind of overkill for my needs, but it has mirrored 1 TB drives. It thought I might need a media server in the near future and wanted the second drive for backup.
