Does any of you really, really dislike Ubuntu 11.04’s new Unity desktop? Is there a reason I should like it?

Has anyone installed Gnome 3 on their Ubuntu in a way that wasn’t completely buggy?

Also, it it just me, or is OpenSUSE’s YaST painfully slow? I rather like OpenSUSE, but it takes something like 10 minutes to install simple programs like Picasa.
