Like a lot of computer products, this probably works well in very narrow circumstances. However, it doesnt work well on my machines for some reason.

Nitro PDF Professional

I downloaded NitroPDF Professional Version 6 online and used it for the trial period. It worked well so I ordered from Amazon. When the package arrived it was Version 5 (which was not reflected in advertisement), and that version will not run easily on a 64bit OS. I contacted the Amazon seller (no response, so far) and the manufacturer. NitroPDF responded within 24 hours and quickly diagnosed problem. They offered a free upgrade to the latest version (upon proof of purchase). I sent them a copy of my Amazon receipt at 10:00 p.m. MST and they responded within 30 minutes with the upgrade.

You can NOT beat a 30 minute turn-around. That is unusual, so I wouldn't expect it every time. But it makes the product that much more valuable to me.

As for the product, it is a very good PDF editing and creation tool. Easy to use with all the major features you'll find in more expensive versions of PDF software. And at almost 1/3 the price of Acrobat(TM) this is a real nice deal. So far I've used the program to create some basic brochures and study guides for my students (at the university level). Being able to create bookmarks and links is an advantage, and it makes self-authoring material pretty easy.

I've also used it to create a couple forms for my research. I did a quick survey form that I used in a short research project I had. NitroPDF allowed me to easily create the survey form, with all types of answer formats, and then create a standalone document. NitroPDF allows me to set the form up to send results to a specific URL or email address. This way, respondents can complete the form, hit the submit button, and it will send the form to me so that I can review the results. Easy to create and easy to use.

This book has a lot of great, helpful information, but be aware that it stops at Acrobat 6. I don't think any of the reviews here mentioned that.

Adobe Acrobat 8 PDF Bible
$44.99
I'm really let down by the book in 2 regards:
1. The print is so small it ridiculous.
2. The contrast of the print to the page color is terrible.

There is decent content in the book but the print is on less than newspaper quality paper. It is extremely hard to read.

Although the content is OK, I'd look elsewhere for an easier reading experience (thus better understanding of the subject).
