Well, I have been a long time linux user, spinning everything from SlackWare to Ubuntu, but I realized the other night that I have never attempted to make a live, persistent USB install, so I decided to devote last evening to doing just that. The good: Ubuntu makes liveUSBs and LiveCDs a since with its usb-creator application. I had a working install within minutes. The bad: As would be expected, it was slow as all hell and borderline unusable. This should be obvious as all IO is happening via USB which isn't exactly the fastest interface in the world, however I was hoping that maybe Ubuntu created some sort of magic using fairies, unicorns and a collection of rainbows to make it work at a usable speed. It seems they lacked the right amount of unicorns. Summary: Don't waste your time.
