Upgrade question

[Patton Echols]

I am still running feisty on my laptop.  I intentionally didn't upgrade 
on the "bleeding edge" but then waited longer than intended.  Part of my 
concern is moving beyond my laptop's capabilities. 

Question:  Is anyone here running Gutsy on a Thinkpad R40?  Any concerns 
or thoughts?

If not, can someone remind me of the safest way to upgrade?  Backup 
first, obviously, and then?

Thanks,

Patton
