Look!!! Another great mobile phone! But wait, it's expensive. But anyhow let's see what this phone has to offer first. The Nokia N91 has an operating system Symbian OS 9 and S60 3rd Edition. A great feature that i like that stands out on this mobile phone from any other at the moment is that it has a massive 4GB hard disk. I like to store lots of games, music and videos on my mobile phone. But this size hard disk is massive, which will leave so much room you will not know what else to store on it. On the casing the keys are situated underneath a sliding part of the case, which i like again because it keeps the dirt out. If you do not think that 4GB is enough, shame you can't upgrade the memory with a memory card as there is no expansion slot. But this phone is great with music as i like music, the phone can play Mp3, AAC and WMA files, which means that if you convert mp3 to WMA you can reduce the size of each song and add more.
There is a good 2 Megapixel camera with video recording that is quite good. To connect to the internet wirelessly you can use wi-fi, which is good if your outside or in work. The mobile can run normal java or symbian applicatins, but this phone is aimed at businesses or business men rather then for the pay as you go customers. We come to the price. It's quite expensive. The price changes as time goes on but if you like this mobile i suggest going on contract and waiting to see if it will ever go on PAYG. Overall a great mobile with cool features. The design is not too bad, plain and smart but is quite long in my opinion. For music lovers and business men then you should get this, but for the basic mobile person, look somewhere else.
