Jeffrey,
Thanks for your response. I am not a techie person and so don't understand
much of what you have said. The computer I am looking at is a Lenovo (IBM)
notebook that says it is "Vista Compable" whatever that means. My primary
use for the computer will be word processing, email and internet, PowerPoint,
and such. I travel around the world doing HIV education and need a smaller,
lighter computer and that is what I am hoping to find in this unit. Frankly,
I don't know what Vista does, but expect that applications will now all be
written for it and so the XP Professional that comes loaded on the machine I
expect will be obsolete before too long and that I why I am wanting to find
out what expense will be involved in upgrading to it when the time comes.
