Summary: You can't beat it for this price. I've never written a review on newegg, but I was so impressed I just had to.
Pros: Unbelievable performance. I had to scan in all our family photos and ended up running four hundred fifty five scans in about 2 days. It only recalibrated itself twice and worked great! I don't know about the software thing, I've never used it, I just use the TWAIN import feature in Photoshop.
Pros: It is a fast scanner that provides very good quality. The software is solid and provides some nice features and lots of tweaks. I like the fact the USB2 cable provides power to the unit, it makes for a clean setup. Very nice unit!
Summary: I am using this as a portable document scanner, and it works...but the Mac software is awful and doesn't integrate into the software I need it to. Still, it is decent quality for the price and very compact.
Pros: Inexpensive, light and small.
Cons: Scanner is quite loud and LED mechanism often illuminates through the other side of the paper. Mac software support is terrible. The programs are not universal binaries and do not integrate with Adobe Acrobat. CanoScan and ScanGear are terrible applications but do get the job done.
Pros: The scanner takes up little space, has decent software and uses the USB for power so there is little clutter. This scanner performs quite well for its price. There are better scanners but you will pay more.
