Along with 'great', I think 'overdue' should apply to your choice for a blog topic!

An item I hope you address sometime, is the concept of UI 'modes'. I don't know the official names, but if I mention 'stylus', 'finger' or 'button', I think most tablet users know what I mean.

I'm familiar with one discussion of UI modes, that arose in a thread about runaway scrolling when using the d-pad button (which I just found a workaround for: I turned images off in the browser to reduce the cpu load).

Personally, I've never touched the screen with my finger, except accidently. Sometimes I would like to use just the buttons, since it only requires one hand, but that's frequently nott possible.
