As a general advice: If you are happy with a running stable system, dont upgrade.
Only upgrade if for a valid reason, like a feature you absolutely need or a bug that already bothers you.
I run a KDE4 based system as my secondary netbook for years now without ever any hitch, putting it to sleep by closing the lid every evening.
