You know something, while the Josh's mock up looks great from a functional end - and seems to borrow form Gravity (Symbian^1 version) - the second one seems to better follow the UI guidelines, and evne introduces a bit of a nuance with the bottom text box that needs to be considered for future updates to the UI guide. In light of this respective thread (since I posted the above paragraph in the other), I would also be more inline with a theme that changes *most* of the look and feel of the UI elements, but then some better attention paid to the usage paradigm or user flow when designing applications. Maemo 5 more or less relies on the idea that most of the interactions are linear and sub-actions are given thru simplistic (end-user perspective) means. If you will, craming the window full of features isn't good, yet leaving a page devioid of them isn't as well. Discoverability should be a defining characteristic of any application, especially in an environment which is emphasizing touch with fingers over touch with styli. Now, looking at this app, I can see off the bat that there should be smaller buttons on the sidebar, and that a gesture-based interface needs to be utilized for interacting with it. This app has a similar user process flow as Fennec/Firefox Mobile. And the UI really should be similar because of it. The "shiny" is another matter. Once the functionality of the UI is met, then let's get a theme and/or some custom elements on the screen - maybe even specfic for that app - which makes sense, and endears some positive opinions. By the way, the sidebar button sizes might not be in the UI document. If not, its best *not* to take the same rule that Symbian^1 has for size, and functions. Working on an N97 everyday, I can tell you that those button guidelines aren't optimial.
