What I am looking for regarding Linux is a distro that has alot of prebuilt
packages that are easy to install and stays pretty close to the latest
developments. I posted a question about linux distros to this forum a
couple of months ago. My expectation is to primarily be booting my USB
drive off of a couple of different laptops. I'm open to trying several
different linux distros as long as it does not become too large of a time

Thanks for this info. I had not heard of this web site. My checks into
Partition Magic seem to indicate that they have developed an activation
scheme similar to Microsoft which makes it difficult or impossible to move
it from one computer to another by doing an uninstall and then reinstall.

I'd do that in a hearbeat if I could but there are some applications which
I run that I don't know of Linux replacements for. I've heard that I can
use GNUCash to replace Quicken but am not sure what I could use to replace
Turbo Tax. But more importantly, I have some stock charting software and
backtesting software and I am not aware of any software like it that is
available for Linux. If I were to decide to stop using this software or
could find suitable Linux replacements then I would change very quickly.

I'm not sure of the implications here. When you say to do it "by hand",
do you mean that I would need to remove the hard drive from the USB
enclosure and put it in a computer such as a laptop to do the install?
Or did you have something else in mind?
Thanks again for your reply.
