I also don't want a multi-mode UI developed. Just simply enabling an external monitor prevents the small buttons (see post #20) and other anomalies that occur when porting a desktop app onto the small internal screen. With an external monitor (and an external keyboard), a ported desktop app becomes more usable even without changes to its UI or changes to Hildon. And I would think video out could be a sort of compromise to accomodate that contingent you mentioned.

But let's not forget that there was also a more radical (IMHO) faction that actually advocated doing away with the D-pad and other parts of the "optimization for mobile apps" on the theory that doing so will deter development of mobile specific apps and thus foster porting of desktop apps. While I would accept video out, I otherwise join with the OP in believing that we should not do anything to harm the mobile optimization, and that certainly includes changing the UI. (Edit: This does not apply to changes made to make the UI an (allegedly) better mobile UI such as Ragnar has suggested. But I know what I like in my wardrobe (obscure musical reference) and I know what I like in my mobile UI. If the UI changes are to be a iphone-like minimalist touch screen with no HW buttons, then I am skeptical and we will just have to wait to see what is the fad and what is the classic that stands the test of time. And hopefully we will have some kind of a multi-mode that permits use of the old UI if we prefer)
