I'm thinking about getting this: HD and using carbon copy cloner. Will that result in me being able to swap out my old drive and put the purchased one in my MacBook, turn it on, and it's like nothing changed? Will applications with licenses run the same (specifically photoshop and lightroom)? Will this count as using a second computer, or will adobe consider this to be one and the same activation? I have a late 2008 MB with 4GB Ram and a 250 GB drive right now. Does anybody have a different recommendation than the above HD? Thanks for any advice or help.
