I have had an HP Scanjet 4670 scanner since they first came out. It is one of those vertical see-through scanners. It works great. You can lay it on a book or use it vertically. It takes up minimal desk space. But the most impressive thing about it, is that it just works well with the Mac. HP provides some pretty useful software called "HP Image Zone." It is composed of several smaller applications that handle fax, scan, photocopy, etc. They are all universal applications and integrate well with other software. For example, you can scan into a sort of clipboard that allows you to drag and drop a scan directly into iPhoto. How sweet is that. It can also be setup to maintain a library of your scans for you. I guess I'm going on about this stuff, because today I was catching up on scanning in all of my important documents and receipts. I was considering getting Readiris Pro, but the HP method is working so smoothly that I'm not sure if I want to mess with it.
