upgrading ububtu

[Agustin.Lobo]

Hi!

A colleague has encouraged me to use ubuntu. I'm now using Mandrake 10.
What I hate most in linux distros is that when it comes to
upgrade you normally have to perform a clean installation
from scratch again. Is this also the case for ubuntu?
I mean, if the current version is 4.10, what will I have to
do to upgrade to the next one (i.e., 4.11)?

Also, I have 2 AMD Athlon 1600+ processors, would this be a problem for
ubuntu?

And finally, do I have to compile the kernel? or, would it be any better
if I do so? In case I had to, is there a good how-to for this task?

Thanks!
