A long time has passed since Nokia dared to introduce such an innovative design that users can admire when looking at the 7500 and 7900 Prism handsets. At a first glance, you might have the impression that there something wrong with the keypad, but the triangular form of the keys is quite comfortable, giving a stylish sensibility to the mobile phone. The unusual bar form of the Prism devices intends to twist peoples minds and conquer the market. A market where most buyers are trendsetters who change their mobile phones according to the fashion trend or simply by their look. Fewer and fewer people are trying to look beyond the design of a handset and choose what is good for them. Thats not necessarily a bad thing, but you must be very careful these days, as the offer is tremendously large.
Nokia 7500 Prism has been announced in August 2007 and made available on the market in September 2007, for a nifty price of 320 USD.
In terms of design, Nokia 7500 Prism, as well as its 7900 brother, cannot be compared with another handset available on the market. The phone breathes style through the glossy material and candy bar form, which are backed by a strange triangular design of the keypad. The phone's form has been cut at 45 degrees on both downside corners, which gives an originality note to the device. The triangular keys may look difficult to use at a first glance, but they are actually very easy to push. The only problem I had was the actual use of the 5-way joystick which is very hard to press/use.
Nokia 7500 Prism features an excellent TFT display, which supports up to 16 Million colors and 240 x 320 pixels resolution. The display is barely visible in the sunlight and lacks any ability to improve its brightness. Even if it's not really a large display, it still is a very good choice for such a mid-level handset. Anyway, such a choice comes at a price, too big I'd say, because the small battery depletes even faster.
Nokia 7500 Prism runs on an S40 platform 5th Edition, thus it lacks an operating system. The new Series 40 5th Edition is a full hardware, software and Application Programming Interface architecture, incorporating Java Platform Micro Edition technology with support for the latest version of the mobile information device profile (MIDP 2.1), and providing an enhanced UI that enables developers to build richer multimedia applications and services for mass market Nokia mobile devices. Nokia's new Series 40 5th Edition enables users to experience streaming video, image rendering, mobile 3D graphics and scalable 2D Vector graphics. Series 40 5th Edition also supports the latest version of Adobe's Flash Lite 2.1, the interoperable platform that enables the accelerated development and delivery of rich graphical mobile content, and includes audio file playback and streaming capabilities that provide audio and music enhancements to both the mobile gaming and multimedia experience.
Users will be able to take advantage of the Active Standby, which is the main feature of the S40 platform, but can also install Java compatible third party applications. You can also find other useful applications such as: Yahoo! Go, Alarm clock, Calendar, To-do list, Notes, Calculator, Countdown timer and Stopwatch. The menu is fully customizable and you can designate any MP3, MIDI or AAC file as ringtone.
Even if it looks so stylish, Nokia 7500 Prism is still a mid-level handset, in terms of performance, thus it lacks 3G connectivity. But you can successfully use its EDGE class 10 technology, that works pretty well for an S40 platform device (128 Kbit/s download and 55 Kbit/s upload).
Processor and Memory
Unfortunately, I wasn't able to determine what kind of processor powers Nokia's 7500 Prism, but my bet is on an ARM9 family CPU running at speeds up to 170 MHz. This is more than enough for such a phone that doesn't have an operating system. Users will notice that navigation through menus is made with ease and no lags whatsoever.
Nokia 7500 Prism surprises through its good quality vibes and widens the possible target of the phone to those that are using their phones as MP3 players. Moreover, the music player that has been included with the phone looks to be the same as the one embedded in Xpress Music series phones. It can play any MP3, MIDI, AAC, AAC+, and WMA file formats and can be fully customized.
I was about to skip this one, simply because Nokia skipped this part too. You develop a good-looking phone, with a very nice display and very good sound and put in such a crappy battery that's too bad, Nokia! The 700 mAh Li-Ion battery is even lower than that of Nokia's 6300 model, which had big problems with the fast depletion of the battery. I could barely make it home with some energy in the batter after 1 full workday. If you're not a heavy user, you'll be able to make it with about 3 full charges per week; otherwise, you'll have to charge you battery almost daily. This seriously lowers the phone's functionality and limits the target of the handset.
I believe that you must actually keep one of these devices in your hand and then tell people about it. Seeing so many cons comments about the Prism's look, I have to say that Nokia managed to turn people against each other (in terms of contradictory opinions, of course) with this phone model, more than any other mobile phone manufacturer did. Anyway, if we are to look beyond its design, we are left with a mid-level phone, with very good audio quality and above average camera. The only thing that will probably bother possible buyers is the price, which is a bit too high for what it has to offer, and the very low battery life.
I won't say anything about its design as people might not consider it good looking at all on the contrary. What I have noticed using this phone is its high functionality and easy to use interface, things that are characteristic to the Nokia brand. Besides its good camera, the sound quality is more than I expected from a mid-level Nokia handset.
The only thing that really bothers me is the low battery life which will seriously limit this phone's functionality and will utterly force you to buy a supplemental battery. Furthermore, the microSD slot card has been placed right under the battery, thus it isn't hot-swappable.
