This scanner is simply the best I have ever seen. The flat bed scanners and the all-in-ones I have used with my Intel iMac G5 all suffered from various problems that made scanning a maddening experience that I couldn't fit into the work flow of any project regardless of how simple it might have seemed. Most scanners are geared for the PC world and Mac software is mediocre at best and usually flat out useless. This scanner and its software are aimed at the Mac market and they have done it the right way.
Following the quick start instructions to the letter, and I suggest you read them all the way through before starting, I had the unit up and running in a few minutes.
It doesn't take long to see the beauty of opening the unit and putting something in to be scanned, pressing the "scan" button and seeing the resulting PDF on your screen within seconds! There are many output and storage options as well, to fit just about any workflow application.
This scanner has become a key part of my day to day work, and I can't imagine trying to do without it.
The unit has a small footprint and for power has a power cord or it can be powered by the appropriate type of USB port making it portable as well. This small size makes the unit mobile, but the tradeoff is that you can't scan bound volumes.
Any group of pages I have loaded in the document feeder (and I have loaded as many as 11) have been scanned flawlessly in seconds.
This is a great product.
