If MS was designing Word now starting from nothing, then without doubt it
would be designed to run from a flash drive. But Word has been around since
the days when 100 MB hard drives were thought excessive and 5¼" floppies
ruled. We have to live with these legacies because major changes would break
backward compatibility. This may change eventually, but with the high
percentage of licensing limited to a single desktop (and possibly a laptop),
having Word run from a flash drive would not be in MS's best interests.

Thanks.

What is the difference between these portable programs, like Portable
OpenOffice, and MS Word, that enables the former to be installed and run
on
a flash drive?
