The LG VX8500 Chocolate dominated the mobile scene for a long time with its sleek, slider design and unique touch-sensitive controls. However, a lot of people--us included--thought the touch pad was a little annoying and required too steep a learning curve. The new LG VX8550 Chocolate, however, is different. Instead of the touch pad navigation array, the LG VX8550 Chocolate has a mechanical scroll wheel. Though the rest of the navigation keys are touch-sensitive, they now have a vibrating setting so they provide a slight tactile feedback when touched. Also, the End/Power key is on the keypad instead of the left spine. All of these design improvements definitely make this new LG Chocolate easier to use.
