When watching the 3.7 preview, you can see that the image is rendered in
tiles; it appears as though each thread takes the next tile on the
current line when it's finished. Perhaps this is all that is kept in memory.

Sony have a 24MP coming out sometime the Alpha 900.

A good scanner with a resolution of 4800x9600 (46 megapixels) will do.
There's a Canon one for 150 euros, so it's not like processing this kind of
image size is uncommon today.
In any case, 40 megapixels is the top range for professional digital
cameras. They're not hard to find. Expensive though...
And here are 160 and 470 mexapixels cameras:

I've yet to see any scanner that goes above 1200 x 1200. (Although many
seem to feature a special "interpolation mode" that gives you more
pixels. WTF?)

My point being, anybody who can afford something like that is unlikely
to try to email it to somebody. ;-)

You should have realised by now that whenever you think that a technology 1)
is impossible 2) doesn't exist or 3) isn't used by anyone, you're just being
10-year late ;)
The interpolation mode is mostly there to inflate numbers, AFAIK.

As I said, a 4800*9600 scanner is rather cheap nowadays.
Actually I have to buy an all-in-one printer/scanner/copier for my dad and
one of my concern is *** exactly *** that he'll somehow manage to scan huge
images (book covers and newspaper articles) and start emailing them to other
people. He already did that with a bunch of 7 megapixels pictures that were
forwarded to him.

Oh, I'm sure high resolution scanners exist. I've just never seen any on
sale. Apparently I shop at a place that only sells ancient technology...

Yeah, exactly. I guess most people don't understand what "interpolation"
actually means. :-P

Hmm. That's kind of worrying them. Broadband technology is nowhere close
to keeping up with that kind of file size...

Of course you saw them on sale, you just didn't look at the resolutions. I
didn't either until I started shopping for a scanner. Your shops probably
sell a basic all-in-one like the Canon Pixma MP610 for instance or the Epson
Perfection line of flatbed scanners.

No but this explains why having lots of RAM and processing power is
important for regular folks. And what about that 500 Mb movie file than
anyone with a recent, cheap, entry-level digital camera can record and be
willing to edit and email to grandma?

And why Word or Vista Aero shouldn't be eating it all. Leaves little
left for video editing.

Oh, what, in a physical shop? I don't often enter those... ;-)

I realise this will probably be met with derision, but... you can edit
video on a "normal" PC now?
[Sure, I'm aware you can do if it you either spend millions on a
high-end video server or just wait several weeks, but I didn't think the
hardware or software for doing this exists at the comsumer level yet.]
