The four-way form factor (shut, flipped open, camcorder mode, mini-notebook style for landscape viewing) is the same as before, albeit with a new silver/dark gray finish highlighted by a mirror-like exterior front panel that hides an OLED screen underneath. Cool. Like the N93 the phone is structured around a hinge at the top of the device, which also stores the 3.2-MP digital camera.
That camera allows you to shoot footage in MPEG4 VGA video capture at up to a DVD-quality 30 frames per second. The phone also supports stereo audio recording and offers digital stabilization so your films won’t be shaky. Opening up the Nokia N93i reveals changes, too, both positive and negative. Most obvious is the flush, RAZR-like keypad  a necessity given the slimmer overall size. There are rubber dividers to give you a better sense of where the key boundaries are in the dark. Unfortunately, there are no dividers between the Call/Edit and Cancel/End Call keys, making it easy to go for "C" and hit the End Call button by mistake, thus ending the application you’re in.
Its 3rd Edition Series 60 Symbian interface is the same as the N93’s and the phone still allows you to upload videos directly to the Internet. I had issues with the slowness of the N93’s menu navigation; happily I didn’t experience any similar problems with the N93i. It simply jumped from one app to another with almost no waiting.
Other plus points include Wi-Fi and 3G connectivity, the superb Carl Zeiss lens with 3x optical zoom, the TV Out lead that lets you play videos shot on the phone on your TV right away, and the LCD screen that automatically shifts from portrait to landscape viewing with a twist of the phone.
Pound for pound, the Nokia N93i is probably the best multimedia phone in the market today.  Manny de los Reyes
