The only reason I am not upgrading yet is the statement I read that there will be no support from Entourage. Even though I am not a complete idiot when it comes to technology, I am not even close to the same caliber as most of the people in the forums (A "geek" coworker told me I was only a "mini geek" at this point), so I would have to do a lot of searching and asking when/if I needed help and I just don't have the time or energy for the possible frustration.
