- Dual SD (even if it makes the device thicker)
- charge via micro USB
- active/hard touchscreen
- Fewer buttons (think apple has the correct idea here)
- better battery life
- improved browser (this will happen with or without nokia...)
- finish the conversion to finger controls... Readon

We do not have a lot of screen space. Now we waste quite a bit for scroll bars etc. Why not use a transparent interface? If you touch in an area that can show a control it shows (transparently). Next touch(s) let you play with the control. After a configurable interval with no activity the controls fade away.

For status areas I would encourage all application to make them hideable via a transparent control (eg touch the lower left corner and a control appears, touch it again and you have a status/input area - much easier than hunting trough a menu)

With standard positions and sizes for transparent controls we could get rid of the need for many of the buttons.

something like this might be workable (user testing needed)
upper left - touch to get menus
upper right - touch to get /fullscreen/minimize/close buttons
lower right - touch to get non transparent status bar
lower left - touch to get non transparent input bar (or toggle full screen input eg for a drawing program)
bottom (above status bar & keyboard, if displayed) - scrollbar
right - scrollbar
top - zoom scrollbar
left - application specific (eg back/forward/home/bookmarks buttons for a browser)
