The Wing features a slider design; just slide the front face of the smart phone to the left and turn it on its side to expose the full QWERTY keyboard. The screen also automatically switches from portrait to landscape mode, but there were a couple seconds of delay, which got to be annoying.
Some of the biggest differences between the T-Mobile Wing and the T-Mobile MDA are in design. The Wing now sports a midnight blue casing and features a soft-touch finish that gives the phone a rubberlike texture.
At 2.3 inches wide by 4.3 inches high by 0.7 inch deep, the Wing is actually slightly thinner than the MDA (2.3 inches by 4.3 inches by 0.9 inch). However, at 6 ounces, the Wing is heavier than its predecessor, and the difference is quite noticeable.
The T-Mobile Wing's QWERTY keyboard now features square buttons (rather than the MDA's oval-like ones) with no spacing between the keys--very similar to the keyboard found on the Cingular 8525. There are also two new, small LEDs at the top of the keyboard that illuminate blue to confirm the Caps or Alt functions.
In addition to the touch screen, you can use the navigation controls below the display to operate the smart phone. These include two soft keys, the Talk and End buttons, a new shortcut to the Start menu, an OK button, and a four-way navigation toggle with a central Select key.
