I was listening to one of Leo Laporte's podcasts the other day (I'm sure many of you know who he is) and he was talking to a caller about running an external hard drive through firewire for his iMac to increase HD access speed and to have a significantly larger drive for storage. He mentioned that over a firewire connection you can actually boot OSX off that removable drive. My question is this, is there any point to doing this with a MBP? I have a couple of external drives for storage purposes, but they only have USB 2.0 connections. If I installed OSX on an external hard drive and then took my laptop somewhere without my external drive what exactly would I do since the laptop wouldn't have OSX on it? Sorry for the newb questions, but they didn't really have time to go into a lot of details on the radio program.
