iPhone is thin, sleek, and dominated by a large 3.5″ touchscreen display bracketed by a cut-out speaker and hidden light sensors (top) and a single physical button (bottom) on the front of the device. At 115 x 61 x 11.6 mm and weighing 135 grams, the device is small enough to tuck away in a pants pocket, large enough to make for easy use of the display, and rather heavy but still pleasant in hand. When the display is darkened in sleep mode, the entire front of the handset is black, flanked by a chromed border and rounded edges all around, and looks like a Star Trek Communicator passed through a minimalist design lab.Most of the side and back panels of the phone are finished in a textured silver metal designed to be comfortable to grip. The lower portion of the panels is done up in black, as are the phone’s controls. Along with that lone front-panel button, iPhone houses a rocker switch for volume control and silent/ringer button on its left side, while the right side is completely button-free. The top panel is home to a power/sleep/wake button, the SIM card tray, and a recessed 3.5mm headphone jack (the source of much head-scratching for me … more on that in a bit). The bottom panel houses a dock connector similar to those found on iPods, and it’s flanked by speaker and microphone grills. The back of the phone features a sensor for the camera set in the upper left corner, and while the black part of the back panel is in fact a battery cover, the battery is not user removable. WIthout delving into the pros and cons of a phone that lacks buttons but compensates with the best touchscreen display on any handset ever, Apple’s near-buttonless design is nothing short of stunning. While the black and silver look that screams “Look at me, I’m an Apple!” is honestly a bit ostentatious for my tastes, it’s ostentatious in a really cool, mysterious sort of way. iPhone is a good looking gadget that looks like it came from the future, especially when lined up next to something like a Treo. After a few weeks of using one, I can definitely say Apple did a (typically) fantastic job on iPhone’s industrial design. The phone feels good in use during voice calls and screen-intensive tasks, and its size and shape is a great balance between large enough for Web and media player use but small enough to tuck away in a pocket. The phone’s 11.6mm profile and extremely durable optical glass front have a lot to do with the whole “easy to tuck away” thing. After several weeks living mainly in my pants pockets without any sort of case to protect it, iPhone’s screen is scratch free and the chrome trim is just a little scuffed up.
