Pros: Upgrading from CS3 and no learning curve (at least for me) to be able to use it right off. I'm sure it has more that'll I'll explore over time. Last reviewer wrote and excellent review and was very helpful. Downloaded and installed without a problem (following the instructions from the last review).
Pros: After purchase, my electronic copy was available within a day. (I had purchased it after hours.) It was a single, easy download, and I never have to worry about losing the DVD or serial because it's always available from my Newegg account.
Cons: The file arrives as a .rar file, so you'll need to download 7-zip or some other freeware to first unzip the compressed file at initial install.
