Excerpt: The Handspring Treo 90 isn't a good entry-level choice, nor is it ideal for gaming and multimedia. But it's a fine fit for mobile professionals and corporate users who need a PDA with an integrated keyboard for calendaring, portable-office work, and communication. The compact, lightweight Treo 90 is easy to carry around and comes complete with a see-through, removable, hard flip cover that protects the 12-bit–color screen.
Conclusion: I really like this model. It's small, the screen is good, and the keyboard is faster than Graffiti. If all that weren't enough, the price is great. If you are looking for a good deal on a color handheld, the Treo 90 is an excellent possibility.
Pros: Excellent battery life, Keyboard is faster than graffiti, Very small, Comes with travel charger, Very good price
Cons: Difficult to use outdoors, Takes a while to get used to the keyboard, Doesn't come with a cradle
