Nokia’s N81 8GB is, not surprisingly given the handset’s name, equipped with 8GB of internal storage memory. This can be used for any data you like, but the penchant of this mobile is for music and games. You might wonder why I am not including photography in the list, but the 2-megapixel camera is one of the aspects of this handset that disappoints. I’ll get to that later, but right now it is worth noting simply that if photos are your thing, there are other mobiles that do a better job.
The N81 8GB is a quad-band mobile with 3G. It has a front-facing camera for video calling. It is a chunky beast in the hand and pocket, measuring 102mm tall, 50mm wide and 17.9mm thick. It weighs 140g, which is rather a lot these days for a mobile phone. A portion of the thickness can be explained by the fact that this is a slider. When fully opened the phone grows to nearly 135mm. The good news about the overall size is that the numberpad is large.
