Palm Treo 750 Smartphone (AT&T)

Design
Under the hood, the Treo 750 features the Windows Mobile 5 operating system and 60 MB of internal memory. The design retains the same popular form factor and QWERTY keyboard as other Treo phones, but with a few subtle, yet significant, changes. The external antenna has been tucked away, and the unit's camera has been dramatically upgraded to 1.3 megapixels. The 750 has been on a diet too--weighing in at only 5.40 ounces, the 750 is one of the lightest Treo phones ever released.

On top of the unit you'll find an expansion slot for SD and MMC-based memory cards, and there's also an infrared port here for line-of-sight data transfers, as well as a handy switch for turning off the phone's ringer. Below the amazingly clear 240 x 240 color touch screen, you'll find a five-way navigator that controls most of the phone's menus and operating system functions, while quick application buttons on either side of the navigator will get you to your favorite applications in a snap. The left side of the unit features a volume up/down toggle plus a handy user-customizable button that can be assigned to any phone or PDA function. The rear of the Treo 750 houses a loudspeaker, as well as the camera unit. A touch-screen stylus can be tucked away on the right side of the phone. Meanwhile, a combined charging, data, and accessory attachment port is housed on the bottom of the unit, as is a standard 2.5 mm stereo headset jack.

Calling and PDA Features
All of the Treo 750's phone and PDA functions are designed to provide an integrated, seamless experience. For instance, you can type in the name or initials of a contact on the keypad to dial them. Or, use the touch-screen and stylus to copy information from an email and quickly paste it into another email or text message. You can even use Microsoft Office Outlook Mobile, a feature that combines email, calendar, contacts, tasks, and notes into a single application.

Staying productive on the road is made possible by the Microsoft Office Mobile suite, which includes Word Mobile, Excel Mobile, and PowerPoint Mobile. Meanwhile, the File Explorer application makes it easy to browse the files on your Treo 750.

All of the latest phone features folks expect are built-in, too, like a handsfree speakerphone, polyphonic ringtones, a vibrate mode and picture caller ID. The 750 comes stock with unique ringtones built right into the unit, and more ringtones can be downloaded from Cingular Wireless' MEdia Net service. The capacity of the unit's address book is only limited by the amount of internal and expansion memory available. Use the Treo 750's Bluetooth capability to wirelessly sync your contacts with your PC. Headsets, car kits and other wireless peripherals can also be paired with the unit via Bluetooth.

The unit's memory expansion slot allows you to transfer music, photos, and video from your desktop. Or, use it to load additional games and applications.

Messaging, Internet, and Entertainment
The device fully supports MMS messaging for rapid exchange of pictures, text and video via Cingular's instant messaging system. The Treo 750's Web browser supports full-size web pages, and you can enter secure pages with 128-bit SSL encryption. POP3 email accounts provided by SBC, BellSouth, Yahoo, Earthlink, Comcast and AT&T Worldnet are all compatible with the 750's email client application. IMAP and Exchange-based email systems are also supported, and you can view photos, HTML, Word, Excel and PowerPoint attachments. With WCDMA/UMTS support built right into the phone, you'll be streaming and downloading at speeds so fast your head will spin.

The 750 also sports an airplane mode, which allows you to safely use the non-wireless functions of a phone (such as music, games or organizer functions) on an airplane during flight.
