I want to keep my dedicated buttons. However, maybe all we will need is Home, Back, and Recent apps. I like the idea of the context menu.
If the official google software says no buttons, I doubt apps will have a problem with it. Archos kind of hacked it on with no support.
I have an Archos 43 Internet tablet and having the soft buttons causes problems with some applications. My understanding it depends on how the developers write it but some don't call for the available screen size and do the whole screen size. Then you get application buttons covered by the android soft buttons.
