Excerpt: This book scanner is simple, light weight and easy to use. I'm not a real computer whiz so being able to basically plug it in and go is perfect for me. For scanning book text it works great and the resolution is fine. I've not tried color photos so I can't really judge it for that, but assume it will do those just as well. I bought this to fill in some gaps in my massive journal library and it works well.
Summary: So far I had a bad experience with this scanner, I was trying to scan a few chapters for my school text book and the color was off and it was blurry so I decided to return it back and get my full refund.
Summary: The scanner did install without any issues on Windows 7. I want to note that it requires a pretty long (~1min) warm-up period so the color temperature of the Cold Cathode lamps is controlled. Unfortunately they aren't using LEDs in this model. I give only three starts because of the manufacturing issues of the glass plate. I detected some spots on the surface and ordered a replacement model. This had also a couple of defects on the glass. This might be only bad luck but.
Summary: This is a great scanner. It would have been 5 stars, except the software that comes with it is very clunky, and not written to Microsoft Windows standards. The "automatic" lens lock is sort of ok, if you place the scanner on a perfectly flat surface. Nice, big buttons that can bring up programs to copy, email, etc. But, it requires a mouse to choose various options.
Summary: Trying to use the OpticBook 3800 with the "beta" driver/app from Plustek for the Mac OS/X is really really painful. Even walking though things with the U.S. tech support got it sort of working but as others have mentioned, it crashes a lot. I got into the habit of scanning about 30 pages maximum and then transferring to PDF and then shutting the app down and restarting to do the next 30 pages. It was just about useless but then....
