Design
The 700wx is colored in the standard treo dark grey and silver color scheme. The 700w is distinguished by a slightly lighter grey shade on its casing. The body is a smooth hard plastic. The top of the device contains the antenna, memory expansion slot, IR window, the famous silencer switch and the stylus silo. The silencer is a very convenient switch that places the phone in silent mode and mutes the ringer and system sounds. On top front of the device above the screen are the LED and phone earpiece. On the Sprint version the LED is only used to indicate battery and charging status, it does not blink when connected or light up when you have new notifications. The Left side has a two small volume buttons and a side button. The backside contains the camera lens and portrait mirror, rear speaker grill and the removable battery cover.
Below the screen are the two soft keys, followed by the 5-way navigator and various shortcut buttons. In addition to the two soft keys, the Start menu and OK buttons help you navigate the device one handed. The green and red phone buttons initiate and end calls, while the red button also does double duty as the power and lock control. Most of the large buttons can be remapped, and the small button on the side below the volume keys can be customized as well, by default it launches the Media Player. In addition, you can setup additional button shortcuts by pressing the blue function key prior to the button.
The keyboard has square thumb keys in a smile pattern arrangement. The Treo keyboard can be very easy to use once you're comfortable with it and you might surprise yourself with how easy it is to type on. The backlighting on the keyboard and buttons is bright and consistent and the keys have a nice white illumination.
Size wise the Treo 700wx has physical dimensions of 4.4" x 2.3" x 0.9" inches (111 mm x 58 mm x 22.5 mm) and weights in at 6.4 ounces (180 g). It pretty much shares the same dimensions and weight as the Treo 650 and 700w.
At three years old now, the current Treo design is beginning to show its age, mainly because of its bulk. The size is mainly due to its large battery capacity and other more powerful features such as the touchscreen. Slimmer smartphones on the market now have to omit functionality and compromise on certain features in order to reach their slim profiles and as a result often fall short on battery life. The 750v showed that the next Treo incarnation would only be marginally slimmer, so it doesn't look like Palm is going to put the Treo on a diet any time soon.

Display
The Treo 700wx has a 2" x 2" inch square touchscreen display. It is a 240 x 240 pixel TFT screen that supports 65,000 colors. The display is plenty bright, even at the middle levek, and holds up well outdoors and in direct sunlight. Being a long time Palm OS users who is used to the larger 320 x 320 display, I definitely found the screen to be a downgrade. I also think that Microsoft wastes a large amount of screen real estate. It's really more like a 240 x 200 display with the ever present title bar and huge softkey space across the bottom of the screen.

There are some aspects to Windows Mobile that can help to make up for the smaller size. There is a system wide font size, and if you have good eyesight, you can set it to its smallest size to fit a lot more text on the screen. You can also enable ClearType, which does nothing for the size, but aliases the text so it looks a lot smoother and can be easier on the eyes for extended reading. Internet Explorer also has a decent full screen mode, which will let you browse without all the oversized toolbars and softkeys. IE also has a 5 zoom levels from largest to smallest, which allows you to adjust the size of text when surfing.

Most Windows Mobile apps will work ok with the smaller screen size. For years the Pocket PC default size has been 240 x 320. Many games, especially older ones, assume this size any will not run on the smaller screen. Fortunately, many popular apps and games have been updated to work with the new screen sizes, though I had a lot of trouble with finding compatible Pocket PC games.

Phone
The Treo 700wx phone uses CDMA wireless technology (850/1900MHz digital) and supports EvDO high-speed wireless data. EvDO allows for data speeds around 10x faster than previous 1xRTT rates and is backwards compatible. The carriers claim that EvDO speeds average around 400-600k, though you are more likely to see around 250-500k. In my area I get about 2-3 bars of coverage, and generally saw speeds of around 300-400k using mobile speed tests. EvDO also allows you to receive calls while the Internet connection is active, on older 1x CDMA devices the phone would not accept calls when actively using the data connection.

You can use the Treo 700wx as a wireless modem for your laptop or desktop computer. Not all carriers may support this feature, and some might even require you to purchase a additional DUN or wireless modem data plan. Sprint does charge extra for this feature and only supports Dial-Up Networking with Windows XP/2000. Fortunately, the included USB cable will trickle charge the Treo when in use, so you don't have to worry about draining the battery when using it
