Um, show me a netbook that plays back 1080P video smoothly. Hahaha!

Look people don't expect a sub-$500 computer to play back full 1080P. And
by the time netbooks can play 1080P at 29.97 FPS, most consumers will be
able to purchase 3D HDTVs at 240HZ and a limited section of video will
have begun being broadcast in 3D HD (ESPN HD is starting some of those
broadcasts THIS YEAR). Blu Rays and video games will be 3D (CES this year
was chock full of 3D TVs, gaming rigs, BD players, etc.). That's
ubiquitous within the next five to ten years.

So lets be straight. People on the bus and train watch video on their cell
phones, iPhones, etc. all the time. These hand-held devices have
revolutionized mass transit, or at least, the experience of it. Laptops
and such simply are not viable on a moving vehicle. A hand-held device is
the only possibility.

And quite simply, HD is nice, but you don't need 2 million pixels per
frame of video when it's only 10" across! For crying out loud, my 24"
monitor with 1080P is so detailed from a normal viewing distance that I
cannot discern any pixels with the naked eye, and I often have to squint
to read any text.

Huh? If it's on "their equipment," then just export the file out of
Keynote to a PowerPoint file. What's the problem here? We're talking about
the iPad, not "their equipment." What if they have their own iPad, BTW?
You never know.

/facepalm

It has an SDK. I.e., any developer in the world can develop applications
for it. Just look at the iPhone. Does that mean it's not limited? Sure,
every device ever made is limited. Linux is limited. The human brain is
limited. If it wasn't, it'd be the GodPad.
