I use the Acrobat XI Pro very happy, it is indispensable for my work as well as private. So I can,. Bs. With Acrobat files Decrease (to save space), I can see pages from a PDF or change the order. I love to do such. Bs. Also comments in PDF files, as well as arrows and borders. The redaction in the Pro version, I use very much to Black z. Bs. For me unimportant elements, the same I do with contracts. The Acrobat is more or less my "most-used printer" because it saves me printouts on paper, and the saved PDF can I manage just as hard copies. Virtually every PDF What I myself make or get, I use the Trim function to remove white space, yes I want information and no white areas. Many papers fluttering into my house, I scan, and save and manage them as a pdf, I can better organize PDF as paper printouts (here each itself is required, own management). I am a home office, and use the Acrobat professionally as well as privately. I have installed the Pro version on my desktop computer and 2 laptops so important to me is the software. (Adobe Reader I have not installed.) The Acrobat is the most expensive software that I use, and I use it constantly. Over the years, one saves a printer for the same money or consumables. I started with Acrobat 4 in 2000, then I bought the 8 series, and now the 11er version. Sure I use some features of the software or never do not know you, but I use it every day - that's essential.
