Let's say you've got a Handspring TREO phone. Or you know someone who does. For example, me. I recently traded my rather large, somewhat clunky TREO 300 in for a TREO 600. For the completely technology clueless, the TREO is considered to be one of the best PDA/cell phone combos out there. It combines the Palm operating system and the power of a PDA with the functionality of a phone (i.e., you can call people on it).

As phones get "smarter," they are able to be used for more than just phone calls (this ain't your grandma's phone, okay?). The TREO is indicative of this basic principle: you can do everything with it but slice bread. Not only can it offer basic functions like a calculator, a calendar, or a to-do list, but it can also serve as an Internet browser, text messenger, music player or handheld video game player. Given all of its capabilities, however, it's hard to know where to start first. So along comes Jeff Ishaq and his TREO Fan Book, a little cd-sized book that promises to help you make the most of "the most advanced smartphone on the market." Hey, he said it, not me.

But to give Ishaq his due, his book does offer a nice collection of information on such things from basic organizational tips to how to use all the extra features associated with the phone. Simple, easy to use chapters, prominently displayed tips, and color pictures all combine to give the reader insight on how to use the phone to its fullest. Which is, after all, the point (unless the point is to look cool carrying a TREO around, which ceases to be cool when you run into someone else who asks you about one of the cool features and you have to admit, "Well, gee, I don't actually know how to work that, but I know its there if I ever want it."). For somebody who has everything - including a TREO - the TREO Fan Book might just be the ticket to helping them learn how to do more than answer phone calls with that fancy new toy.
