I see that you recommend upgrading to CS5 from CS2... I had already upgraded to CS4 from my full version of CS2, and the CS4 upgrade will not run because it's original base version was CS2... So pretty much anyone who has been a loyal user of photoshop since before CS3, and who have upgraded from older versions, cannot use their CS3 or higher with Lion because it doesn't work??? I do not want to have to buy a new full version of photoshop. Won't do it.
