Hot-swapping of USB devices is now more stable, a very welcome addition for those [who] encountered the USB reboot issue present on previous models.
It would be interesting to see what RasPi did to improve (but not solve) the USB hot-swap issue. They probably just increased USB +V capacitors, but didn't add inductors. I have a Model B rev 1.0 so it has locations for polyfuses F1 and F2, which gives the user flexibility.
