I bought this printer/scanner for a "portable" scanner to take on the road with me to client's homes to print things for them to sign and to scan documents while I was there. I needed a machine with a small footprint (this one is 16"x14"x9"). Comes with good software, but I use Adobe Acrobat 9.0 Pro and it works great with that as well. I have Vista 64, and it works great with Vista, no problems. Good lightweight printer, great scan quality, if you don't mind not having a document feeder (I didn't want one, for easier portability), this is an awesome machine.
