on that stylus issue, i guess it depends on how one expect to use the device.
and as always with a open ended device like the tablets, those expectations will wary to a great degree.

Dear Nokia:
I heard the most preposterous rumor and I was hoping you could clear things up for me. Is it true that none of your future hand-held linux devices will have a stylus and a stylus holder? Thanks in advance.

Now, people seem to prefer capacitive screens in general. To ship a capacitive device, having stylus UI elements is obviously a very bad idea. For a platform, there can of course be many different devices, with differing screen technologies. But branching the UI software would also be a bad idea.

Because a stylus sucks for mobile usage. Simple as that.
Now that we have all that covered, let's get on to the real deal, pupil-tracking pointers. Fast, no hands needed, does not obscure the screen, high resolution and much more uniform among human population than fingers. We just need a higher resolution user-facing IR sensitive webcam.

Will any future Nokia hand-held OMAP3 linux devices have resistive touchscreens? If so, will any of them have a stylus and a stylus holder? And lastly, will these same devices have screen resolutions less than 800x480? Thanks in advance.

Resistive screens support styluses, capacitive do not (except special ones, but that's a bad idea).
I've only ever touched my tablet screen with my finger (or nail) or the supplied stylus (since it's always to hand in the in-build stylus holder).

If I no longer had a stylus option, touching the screen would still be my last choice. But with laptops, a touch pad is my first choice. So, here's a front and back picture of some 2002 technology (the touch pad of my poor, dead Evo N410c. I miss you). It's wafer thin, cheap and I wouldn't need the buttons. Why can't something like this be on the backplate? Nokia is already going to need one for their netbook. Just have someone reach over to that assembly line and slap it on my tablet. Then you could capacitate till the cows come home. But just to be clear, this would be a compromise; I would still prefer a stylus for my RX-81.
