Mac OS X Tip of the Day: Scanning
Many people think that you can't scan natively in Mac OS X. Au contraire. There's a wonderful application called VueScan that does a remarkable job of scanning. It supports a ton of scanners (SCSI, USB, FireWire, Slide, Flatbed, etc.).
I use it all the time with my Nikon LS2000 and while the UI takes some getting used to (it is very utilitarian), I find that I am much more productive now than I ever was with the software supplied with the scanner.
Definitely one of my must have apps in Mac OS X - with it, many Macs are becoming Classic free zones.
