It does. It's only double the size of the CD iso, rather than six times
as is the case with the regular DVD, so an easier download proposition.

I think the download bandwidth is probably the more important factor
here. $5 will get a 2GB usb drive today; next year the same amount will
probably get a 4 or 8GB drive. Year after that you probably won't be
able to even find 2GB drives.
So, you probably don't need to be as strict about the size limit over
time, the way we have to be for CDs.

If we have the machinery to produce language-specific CDs, could that
same machinery be used to produce language-specific USB isos? If so,
then only one language per image is necessary. Looks like that'd give
back a lot of space.
Would be nice to see a diff of the DVD manifest vs. CD, with package
sizes, so we can see what packages would give back the most space to
As far as stuff worth adding, maybe look first at apps we've had to drop
like gimp and various office tools. A few more games might be nice.
I'd love to see Inkscape included. What about frequently needed
proprietary codecs or drivers?
