There are plenty of other options out there, such as Aperture (Mac only), Microsoft Expression Media, even Adobe Bridge which is included with Photoshop, just to name a few. The key is to find a tool that you’re comfortable with and use it regularly, making it second nature to process your images every time you shoot. It’s more useful when you work on multiple computers, but even with a single computer, you’ll find that you are spending more time on shooting and image editing and less time on sorting and organizing them.
