1) Apple iPhone 3G ($199 - $699) -- With 15,000 applications and counting, Apple's latest iPhone is gaining an amazing amount of popularity. The battery life still leaves much to be desired as well as the super breakable (and still not covered under the warranty) LCD screen, but the ability to check email, phone, the weather in multiple cities, use a GPS, and find a restaurant nearby are enough to keep you addicted for hours.
