All about symbian has compiled a list of the Top 10 Classic Smartphones. They compiled the list by looking at what new cutting edge features were introduced in those devices at the time of their release. Of the chosen devices, half of them run various versions of S60! I am especially honored at the Number 1 choice of top most ground breaking Classic Smartphone because it was the first device that I worked on when I started working at Nokia.
Dotsisx over on Symbian-Guru posted that she expected to see devices such as: N82, N91, and the Nokia 6600 on the Top 10.

Mobile devices are advancing so quickly, just look at some of the technology added in devices over the last couple of years makes me stop and think about how far these devices have come. Wifi, VGA resolution video recording and playback, GPS chips built-in, High Resolution Cameras, TV-Out display, native MP3/AAC and other audio codec playback, large internal flash storage, large memory card support, Web browsers with capability to render real webpages not just mobile ones, etc. etc. the list goes on. These things have become standard in current S60 devices but just a few short years ago we could only dream of using them in our mobile devices.
My question to you readers is: What are your Top S60 devices that you think were groundbreaking when they were released and why? Also what new features are you looking forward to trying out on future S60 devices: S60 Widgets, Flash Lite 3, Touch UI, something else?
