Excerpt: The X51v has kept the same design as the X50 which is mainly a sleek piano black with a silver edge. It measures 73 x 119 x 17mm which is 1mm thicker than its rivals but makes up for this by having curved corners making it more �pocketable�. The rubber grippy bits at the side are helpful for ease of holding in one hand. New features are the biggest part of the X51v�s make-over without a doubt.
Pros: Slightly larger screen than others on the market Good looking design
Cons: Slow performer Behind on features that other models already have
