Intro

At the end of the 2006 CTIA show last April, we chose the Sony Ericsson K790a as the best cell phone of the show. Since we don't get the opportunity to put all the new handsets we see at shows through a full range of tests, there's always a danger that our favorite picks will wind up as lemons once they hit the real world. In this case, however, we're happy to report that for the second year in a row, our first impressions were correct. Like the Sony Ericsson W800i that won the top CTIA prize in 2005, the K790a is one heck of a cell phone. Inside the stylish and sleek design, you'll find a wealth of well-designed and high-performing features. And as Sony Ericsson's first Cyber Shot-branded phone, the 3.2-megapixel camera is top notch. There were a couple drawbacks here and there--it lacks world phone support, and the navigation controls took acclimation--but otherwise the K790a is a solid device all around. Of course, with no supporting carrier at the time of this writing, the GSM K790a will cost you. At present it's priced at $499.

Like most of Sony Ericsson's cell phones, the K790a sports a simple candy bar form factor. Though it's almost perfectly rectangular, it still has a sleek and stylish design that's sure to catch attention. What's more, the black and gray color scheme accurately reflects the high-tech features inside. The K790a is far from compact (4.1 by 1.9 by 0.9 inches; 4.1 ounces); a solid construction and comfortable feel in the hands is a worthy trade-off. Just be advised it won't fit in smaller pockets.

Like many Sony Ericssons, the K790a has a brilliant 262,144-color display that richly captures whatever content it shows. At two inches diagonally, it takes almost half of the real estate on the phone's front face, while the 240x320 pixel resolution makes for eye-popping colors and sharp graphics and animation. You can change the brightness but not the font size. Below the display is the main navigation array, which is a throwback to the controls on the Sony Ericsson K700i. A five-way joystick doubles as a shortcut to four user-defined functions, while the two soft keys open the recent calls list and the main menu when the phone is in standby mode. You also get dedicated Back and Clear buttons, a key that launches the Web browser, and a nifty control that opens a submenu of user-defined shortcuts and a list of upcoming calendar events. Overall the navigation controls were tactile and easy to use, but they are squashed between the display and the keypad buttons. As a result, they take some acclimation due to their relatively small size.

The K790a has a simple yet attractive design.

Speaking of keypad buttons, we were pleased with those on the K790a. While previous Sony Ericssons such as the W300i often slipped in the design of their keypad buttons, the K790a's are a big improvement. Rectangular in shape, they're large enough for most hands, and since they're raised just above the surface of the phone, it was easy to dial by feel. They're brightly backlit as well, so dialing in dim situations was not a problem.

A music player button and the Memory Stick Micro slot sit on the left spine, while the right spine holds a volume rocker and a camera shutter control. The most interesting feature is on the back of the handset, however. Just slide down the back cover to expose the camera lens and self-portrait mirror. Above is the large flash, which, believe us, is like no other flash we've seen on a camera phone (see Performance). When viewed from behind, the phone looks very much like a standalone camera; the camera shutter even shifts to the top of the phone when it's held horizontally. Completing the exterior is a small speaker next to the camera lens.

There's a lot to tell about the K790a's innards, but we'll get the basics out of the way first. The phone book holds a respectable 1,000 contacts, with room in each entry for five phone numbers, Web and e-mail addresses, a work title and company name, work and home street addresses, a birth date, and notes (the SIM card holds an additional 250 names). You can organize contacts into groups and pair them with a photo for caller ID. You can pair contacts with a ring tone as well, but oddly only 16 72-chord polyphonic tones are included. Fortunately the K790a supports MP3 tones, and you can even use videos for caller ID as well. Other essential offerings include a vibrate mode, text and multimedia messaging, an alarm clock, a calendar, a task list, a timer, a stopwatch, a calculator, a notepad, and a voice memo recorder (space is limited by the available memory).

The K790a also comes with a wealth of business-friendly features that should please most worker bees. You'll find full Bluetooth for connecting to a wireless headset or sending files or your electronic business card to another Bluetooth device. And like with many other Sony Ericssons, you can use the phone as a modem and use the Bluetooth feature as a remote control to connect with other Bluetooth devices. Other high-end goodies include a speakerphone, an RSS newsreader, an infrared port, PC syncing for contacts and other files, USB cable support, e-mail, voice dialing, and a code memo for storing passwords and other secure information.

While Sony Ericsson's Walkman phones focus on music first and photography second, it's not surprising that the company's Cyber Shot phones do just the opposite. And as the K790a is the first Cyber Shot handset we've inspected closely, we can report that it rises to the challenge successfully. In short, the 3.2 megapixel K790a is the most advanced camera phone we've reviewed, surpassing the Nokia N80 and the Nokia N90 in features and in performance. It marks a very long leap in the direction of making camera phones truly functional devices rather than just a fun novelty. While previously we thought cell phones and MP3 players made more logical convergence devices, the K790a has caused us to rethink that theory.
