I updated to Pro 8.0 a few months ago. Adobe Standard 7.09 (well, actually it was 7.0, and I had to do about 6 patches to get it to .09) that came with with my Fujitsu scanner (a very good product by the way). Now, there had been no security updates for 7.09 for months and months, which is the reason I bought pro. Lo and behold, three months after after acrobat 8 pro is released (you can't buy standard for the mac anymore; that would be too cheap!), Adobe releases 7.1, which has security updates. This seems like absolutely unethical behavior. Now that 9 is out, with useless features (how many users really need to put flash in their adobe documents? Come on! And a lot of this collaborative stuff was in Adobe 8.1 already), they can end-of-life the 7 series. So security updates will come out quickly for 9, and slowly for 8.1 (I bet). The cost for me to update my several month old Adobe Pro? $159. $159 for an update! Geez, generous. This program not only eats money, but devours memory and disk space like a champ. Avoid, avoid, avoid. I'm sure 9 will be worse. And it is unclear how to do the simplest operations. I was trying to add text, and it told me I didn't have the font in my system, therefore I couldn't add text. Well then give me an easily found setting to use some other font! And recently distiller crashed trying to print a simple document. Grrr, I hate this program, and this company.
