My experience has been if the CPU or video chips are too slow, then it
drops frames. It depdends upon the program and how slow it is.

Well that says a lot. It says (to me) that there is some sort of graphics
acceleration with hardware mpeg-4 (aka MPEG-4/Divx/H2.64) decoding.
The fact that it only decodes m4v, mp4 and mov files means very little to
me, it's just a choice of software unwrappers.
It also explains why there is no flash decoder, flash is also just a container,
but it can be used to contain so many video formats that the iPad could not
process at anything useable that it was simpler to go without it.
Anyone else remember the days when Apple licensed the Soreson (sp?) codec
and there are bunch of quicktime videos that ONLY played on Apple products?
I doubt they want to be on the short end of that stick.
>720p is technically 'HD'
Ok, It's DVD resolution, but I think DVD's were 720i.

I agree with that, one having had a team leave a bunch of powerpoint and
word docs with a "strategic partner" in Korea and have them show up on
a competitor's website. It was flattering, but (a lot more than) annoying.

There is a lot of competiton out there, and a lot of different devices
to fit everyone's needs.

But that ruins all the fun. It makes for long running discussions like
what we used to have on here before Mr Bill (and others, mea culpa) moved

New word I coined 12/13/09, "Sub-Wikipedia" adj, describing knowledge or
understanding, as in he has a sub-wikipedia understanding of the situation.
i.e possessing less facts or information than can be found in the Wikipedia.
