Ubuntu 12.04 – Should I Upgrade?

I’m contemplating on whether I should upgrade to 12.04 or not. I’m already 100% sure that I won’t be using Unity, but the possibility of having Gnome 3.4 is making me a little curious. Should I jump the gun? I really don’t notice much of a difference when I upgrade and I’m a bit scared of upgrading from a previous version; usually I just wipe Ubuntu and reinstall. But that would mean reinstalling every application, reconfiguring settings, redownloading gnome extensions, etc. Also, I’m using VMware Player and I’m not completely sure how that’ll turn out. I guess I’ll try it out in June when my spring semester ends and the need for a Windows VM becomes unnecessary.
