Nuance Power PDF 2 review - PC Advisor. If I had to choose the most valuable document software on my computer that wasn't a document creator like Word or WordPerfect, it would be Power PDF 2. This software is easier to use than Acrobat, less than half as expensive, and does everything a lawyer needs to do with any document. In a world where efiling PDF documents has become the de facto standard, it is the only document management system you need. It does much more; but, I use it every single day to organize, store and create pdf files for filing and management. I use it to digitally sign documents for filing with Courts, conversion from any format to any other format, and much more. If you aren't willing to spend around a hundred bucks on software to make your law practice much more efficient and capable, you shouldn't be practicing law. Futurelawyer gives this wonderful software his highest recommendation.
