Picked up a Kingston 1GB USB today - earmarked for DFLY
research on that issue.

I am sure that I can get it into 256, not sure about 128.

At current trends, 256-512 would be 'good enough',
and larger would allow a good deal of workspace
for stored docs and such..

Keep in mind that - realistically - it is probably 6-10 months out
(my personal guess) before DFLY is ready to do 'serious' chasing
of 'market penetration' (if such term applies to F/OSS).

512MB - 1 GB are already quite affordable, 2 GB on the shelves,
(4 GB are usually CF-size micro-HDD).

ACK, as in QNX old demo.  Connectivity, GUI, browser, and all.
That sort of item (1.44 MB) is really a pure 'demo' -
*Very* selective strip-down. Oh - you could do a CLI-only
for an embedded app in less than that - but nothing that
would be attractive to today's users.

AFAIK 256 is pretty standard in commodity boxen, 512 'soon', 1 GB
no longer just 'power' users.

Again - cast the projection out about 6+ months - not just today.

Target on USB.  Far more universal already than FDD ever were.
