Consumer review site Reevoo.com says manufacturers need to think carefully about the user interface before incorporating a touch-controlled screen. After asking more than 19,000 buyers for their opinions, Reevoo.com found that only two out of the top ten devices were touchscreen phones - and five out of the botton ten phones were touchscreen models. The top-rated phone was the Nokia 5220 XpressMusic, while the highest-rated touchscreen phone - Apple's 3G iPhone - was in seventh place.
