Nothing can beat having a great Linux distro installed on a super-fast hard drive, with all your favourite apps configured just how you like them and all your files at your fingertips.
But this has one major drawback: perfect as your setup is, it's also just one machine, and sooner or later you'll be forced to leave that computer behind and use something else.
Something that might run Windows. Something that might not even have Firefox. Because no one likes being parted from their data for too long, techradar present a smarter option: store it all on a USB flash drive.
