Preface. I have had an e71 for about 9 months now. And, so far I have mixed feelings about the device. On one hand, it has an awesome form factor, solid construction, a decent camera, a great twitter app (Gravity), and can handle just about anything I throw at it. But on the other hand, the interface is pretty poor (even after applying some nice themes from Tehkseven). As it stands today, I am definitely not going to be getting the E72 and will probably switch to a Blackberry if the next generation doesn’t feature a radically different interface. Rather than wait around for the next generation to show its face, I figured I would put together some interface concepts of what I would like to see out of the device that follows the E72.
Assumptions. I made a number of assumptions when putting together this concept. First, I assumed that the next generation E-series would, at the minimum, have the same screen size as the Blackberry Bold. So, I created the concepts with a 480×320 resolution. Second, I created the following concepts assuming the device would have a capacitive touch screen. As a result, the icons are bigger and there are more contextual menu items. I think the concepts would work without touch navigation, but that is too short sighted for my liking.
The concept. I broke the concept into 3 screens: the home, the contacts page, and the contacts page with the new launcher.

The home screen is divided into 3 parts: the top bar, the notifications widget, and the launcher (the bottom bar). The top bar has the signal information, carrier information, and date/time. This is pretty standard. The second piece of the home screen is the notifications widget (the big white box). This section provides a hub for all your notifications: twitter, gmail, facebook, text messages, IMs, calendar, etc. It would be completely configurable. From any message, you could jump to the next message using the arrow button or go directly into the associated application by clicking “launch app”. The final part of the home screen is the launcher at the bottom of the screen. The launcher acts as both a toolbar (think Windows 7) and a application switcher. Any apps that are active are highlighted with a subtle white background. The launcher can hold an unlimited amount of applications and can be scrolled right-to-left with a flick of the finger. The down arrow on the right of the launcher provides a hot spot to minimize the launcher to get a little more desktop or application space.

The next screen is an example of what the contacts screen would look like. Nothing out of the ordinary. You have a simple menu key on the left and a close (or hide) key on the right. This is consistent with the current e-series. Of course, screens like this would have kinetic scrolling with the flick of a finger.

What is unique about this concept is that you can pull up the launcher over an running app. You could do this using the top key of the directional pad or by simply flicking up from the bottom of the screen. This would allow you easy access to your applications.
Wrap Up. First a few qualifiers. This is only a concept. I am in no way affiliated with Nokia or Symbian. This is a derivative work. All icons are property of their respective owners. A lot of these concepts are borrowed. The home screen is definitely similar to what is currently being shown by Samsung’s Touch Wiz, Motorola’s Blur, Symbian’s s60, and Blackberry’s OS. Being that is a concept, there are a lot of holes. But, I definitely think it is a good point of conversation as to how future e-series devices should work in the future.
