It depends what kernel you're using. LVM2 is part of the kernel.org
tree now, so I recommend using that if you're running a 2.6 kernel. If
you're running something earlier, you'll probably need to apply patches
to get either LVM or EVMS; in this case, I suggest using LVM just
because it is fairly similar and compatible with LVM2, so you've got an
upgrade path and you can continue using your existing LVM knowledge.
As nice as EVMS is, don't bother with it unless you have a very good
reason to. It didn't get accepted into the kernel.org tree when it was
submitted, and now that LVM2 is in and well maintained, it certainly
won't be going into the kernel.org tree in the near future.
And, as always, make sure you have good backups.

Agreed. Concatenating drives is a foolish move for 99.999% of people.
Don't do it. Volume management does not require or encourage this sort
of configuration, but it doesn't protect you from bad decisions either.

Volume management? Have you used it for a significant period of time?
It's incredibly useful, especially if your filesystem allows on-line
resizing.
