V7 advantages over V5

[Brushman]

At the risk of asking a daft question but what advantages does Acrobat V7 have over Acrobat V5? I currently print to the Distiller fom my application to produce a pdf for output by others, sometimes a composite for cmyk jobs or pre-separated and this works fine so why should I upgrade, is V7 quicker, more reliable................ I use XP pro on a 3Ghz machine with 1 gig ram

I read this review linked to from Adobe's website

http://www.pcmag.com/article2/0,1759,1751158,00.asp

and couldn't actually see anything to grab me from the standpoint of a designer preparing jobs for offset printing.

However, from Adobe's website (

http://www.adobe.com/products/acrobat/creativepro2.html)

I found this:
* Achieve reliable print output with improved preflighting features as well as the capability to correct the most common errors that occur in Adobe PDF files. For example, with Acrobat 7.0 Professional you can convert colors to CMYK, fix hairline rules, and flatten live transparency without having to create a new Adobe PDF file.
* Minimize prepress errors with new warnings for total ink coverage, rich black detection, and overprints.
* Control inks, including remapping spot colors, using the same Ink Manager found in Adobe InDesign® CS software.

Some of which could be very useful for a designer.
