We do not have a lot of RAM in our Desktops, which are older models. Mine
has 512 MB and my daughter's has either 384 MB or 512 MB (I can't remember
and she is using it now)... However, we do have more horsepower than your
laptop. I use GNOME 99% of the time and it's running well. My box has a
Celeron 2.6 GHz and daughters box has a P4 1.6 GHz.

I used FF2 for a few minutes, while testing a Ubuntu Live CD, before I
shipped it to a friend, Monday. From that quick test, I think FF3 is FAR
more advanced and so far I haven't seen any problems, while surfing with

Our Router/Firewall is a headless  IPCop and I will leave that one alone,
since it's working properly.

Well, as you gradually update packages, if you update everything, you will
be on 5.2.  If you only update a few packages that you feel are necessary
for security, you will continue to be on 5.1.

If you can backup the data on your laptop, give it a shot. Do not upgrade
anything, without backing up. HTH
