I want to update to OSX Lion I'm waiting on my 8GB of ram and my time capsule to come in before doing the upgrade. I have a few questions is it worth it to do a clean install? it doesn't seem too hard from the youtude videos? Also, in the videos I seen about clean install when Lion boots up it has an option about using TC does this mean it will then upload all my back up files from the TC to my computer? I just don't fully understand the getting my files back after wiping my hard drive clean and if it will have an effect that it was uploaded into TC on Snow Leopard and now to Lion.
