The Sony Ericsson Z750i was announced toward the end of Q1 2007 and it marked the Japanese-Swedish company's foray into the HSDPA market. At this time, if you're thinking the Z750i looks familiar, it is. In fact, you'll be hard pressed to find any major differences between the Z750i and the earlier Z610i.
We have to admit sheepishly that we really like the stylishly designed Z750i. Part of the reason, we suspect is the Japanese "kei tai" (mobile phone) allure which has typically followed the clean and simple design philosophy.
Like the Z610i, the Z750i retains the seamless mirror-like surface with a hidden OLED screen. When activated, the screen illuminates to give the effect of a floating display on the surface. If you look at it from an angle, it appears as though the various "layers" of the screen extends into the handset, giving it depth and a three-dimensional feel. The OLED screen displays incoming message alerts and calls, music information and in idle mode, the time, battery level and signal strength.
The only cosmetic differences we find between both handsets are the Z750i's matte-plastic backing, taller spine (the part of the bottom lid that extends above the top cover), inclusion of call/end keys and the slightly different layout of the buttons.
That said, the buttons on the Z750i are easily one of the best in the market today. The alphanumeric keys are large and provide excellent tactile feedback. The rest of the control buttons are also adequately sized to provide reasonable sense-of-touch. There are three quick access music controls on the left edge of the handset. Two of these buttons double as volume keys.
