Well, as suggested by the title of my review, this phone is impressive (feature wise) yet puts you down (designs not so great). This is what I think after looking at it in various websites and pictures and what I hear about it.
This phone is great feature wise.
Lets have a look at some top features of Nokia N91:
4 gb Memory basically built for music files;
ofcourse a good media player which supports MP3, AAC, WMA and M4A;
pausing playback when picking incoming calls and resumes playback after hanging up;
integrated 3.5 mm stereo headset jack;
2 Mega Pixel Video Digital Camera;
USB connection and the USB connector is a plain, non-proprietary mini USB port;
Connectivity is good in the N91, it offers GSM/GPRS/EDGE 900/1800/1900 MHz connectivity along with 3G. Nokia has also managed to add Bluetooth and Wi-Fi 802.11b into the N91, and also 802.11g which is not so common with mobile phones.
Surely, all these make it a great phone. Its a true competitor to SE Walkman Series, especially W950i (which also has 4gb memory, but no camera). Even portable media players will be affected by this phone!
The thing that puts it down:
Design. Its not so great. Looks huge, and too congested. Surely this will not be a choice to those who show off with their phones. Infact, all the N-series phones are too big. Nokia should see and come out with better designs.
Also the price is tooo much. It is prohibitive.
