I think far more synthetics are used, nowadays. And, things are
designed with short expected lifetimes.
The "rubber" feet on my external Sun enclosures all turn to *goo*
over time. First time this happened, the device in question was
sitting on a nice piece of wooden furniture. What a mess! I now
put *felt* feet under any device that sits on any "solid" surface
(I wonder when I will discover that the felt turns to some obnoxious
substance over time??)

I use a BT keyboard and mouse on my tablet PC's. Normally, the
pen interface is sufficient (navigation, annotation, etc.). But,
when I *really* need to "talk" to them, fingers and pens just
don't cut it.
(Unfortunately, my BT keyboard and mouse are both "full size".
I need to find smaller versions of both -- esp the mouse)

Over the years, I've used various "pointing devices" for presentations.
I have a couple of projectors whose remotes include laser pointers.
But, I am always leery of using laser pointers and the chance for
abuse (sort of like having compressed air in a shop!). And, requires
*my* projector be present (though I have one projector that is about
the same volume as a small laptop)
At one point, I enjoyed <

(essentially, a wireless trackball). But, it was bulky, required
a special "receiver", etc. (It's main advantage was you could use
it on a foreign PC or projector without requiring a special driver)
For large groups <

was excellent! Especially when you configured the gestural interface!
Even without that, it was a spooky feeling as it *looked* like you
were actually moving the cursor AS IF by a laser pointer -- even
though this was often "coincidence" (i.e., the gain of the gyro
happening to make your motions "match" that of the cursor). But,
after some of these "grew legs" on a couple of different occasions, I
decided their novelty was too expensive for me to continue supporting!
<grin>

worked well on a whiteboard. With the "capture pack" (essentially,
holders for four colored whiteboard "markers" plus an "eraser"),
it was easy to annotate and revise presentations based on feedback
from others in the room (folks seem obsessed with watching as *their*
marks are added to the video -- it encouraged more participation than
was really necessary! :-/ )
<
http://www.wheelermachines.com/philips_5282.htm> is my latest
choice for "presentation controller". Corded, unfortunately. But,
the trackball is easy to use to manipulate the cursor "one handed",
plenty of buttons to preassign to key actions ("next", "previous",
"up", "back", etc.) -- I think there are 12? buttons on (or under)
the thing!
Before a presentation, I print up a cheat-sheet of its contents and
tag each image with a barcode. So, during the presentation, I can
find the "thumbnail" I am looking for and scan that barcode to
quickly bring me to a desired point in the presentation (much
more elegant than having to navigate a menu or leaning on "next"
and "previous" while folks watch images flip past!)
But, the most appealing is that it allows me to tag the presentation
with live audio -- so I don't have to stop to type up notes from
those present, etc. An "ideal" solution would have an open mic that
also fed into a transcriber so comments and questions could be
recorded "in sequence" with the presentation for review, later.
[Even *more* appealing is NOT making presentations! Or, make
presentations that interact with the viewer so *you* don't have to!
