Kevin Kelly's recommendation for the best personal color book printer is Blurb. Blurb produces color books very similar to the iPhoto books you can order from Apple. Using iPhoto Books is slightly easier than using Blurb's software, particularly if all your photos happen to already be in iPhoto, but it works well enough. The idea is that you can drag images (photos or illustrations) into template book pages, add text or captions where you want to, then hit a button and have the finished book mailed to you. (all these systems work with PCs and Macs)
