A review of the Nokia N81 multimedia slider has been posted over at Trusted Reviews. '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. Also, while many sliders have a ridge at the bottom of the numperpad area the N81 does not, so it's easy to get to all the keys and texting at speed is unproblematic. There isn't a ridge on the outside of the casing either, so pulling and pushing the slide means using the screen section for leverage. You don't want to drop a thumb onto the button area for this job as you'll end up activating something or other.'
