Won't play at all? or you just won't be seeing all the pixels? I've
never rented HD video from ITMS, the one and only time I rented
anything from there was a SD video, and my iPod Classic played it
fine. All of the other video on it is either ripped DVDs or stuff I
pulled off my TiVo and converted to mp4 myself. Apple does sell
component video cables for the Classic and iPod Touch/iPhone, which
makes me think that they are probably capable of decoding at least
something approaching HD, though I would accept that they probably
don't do 1080p, which is not, as I understand it, part of the HD
'standard' as defined by whomever defines that sort of thing.

From their website:
TV and video
. Support for 1024 by 768 pixels with Dock Connector to VGA Adapter;
576p and 480p with Apple Component AV Cable; 576i and 480i with Apple
Composite Cable
. H.264 video up to 720p, 30 frames per second, Main Profile level
3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio
in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps,
640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC
audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file
formats
720p is technically 'HD'

Sure, it's the 'standard', but personally, if I was leaving a copy
behind, I would either leave a printed copy, or a PDF, something a
little less editable. Using their equipment, I would either plug into
their projector, or be prepared, bringing the file in a format that I
know they can deal with, either save out of Keynote in PowerPoint
format, or PDF, which should be viewable on anything the customer
would have.

And that is closer to what I would probably get for my needs.

At that point, I would get it if I wanted the geek toy rather than
something I would have a 'business' need for. My MacBook Pro fills
all my business needs much better than I see the iPad doing.
There are plenty of reasons to not like this device, I would rather
just discuss the points we know about rather than bits we won't know
until it actually hits the street and gets dissected. There are bits
we do know, at least as much as we can trust the marketing literature
that Steve has made available to us.
