Those pictures don't prove anything. Only the keys are similar. I already said that Nokia has used the slim keys in N91. As for the navigation keys no key matches those on K550i. And in case you're forgetting a phone has a top, bottom, left, right and back side as well and you'll hardly find a similar looking part there. Plus the phones hardly resemble each in real life.
As for the "yeah right" comment, I can prove anytime that N82 is better than K850i. It has better display, stereo speakers, wi-fi, GPS, 3.5mm jack, higher camera camera with Carl Zeiss and brighter xenon flash, higher resolution and much better quality video recording, motion sensor that not just works in games and media player but can be used everywhere to change the display mode and camera image orientation. Plus being a smartphone the motion sensor can be used for a lot different purposes. The media player supports more formats, the headset has a remote control, web browsing is infinitely better on the S60 web browser, no limits for the phonebook contacts and messages, active standby mode and multimedia menu for instant access to favourite apps, automatic voice tag creation, support for bluetooth wireless keyboards and tv-out feature, uPnP for streaming music wirelessly, the list goes on. Do you still think K850i is better than N82?
