I used FedUP to upgrade to F22 and had no issues. The new Plasma looks great IMO; yes things are a bit different which will take some time getting used to, and I'm sure I'll notice a glitch here and there, but it is extremely nice. I have a few apps which have issues (Insync doesn't show up in the notification area), and I'll report those upstream.

It is a bit slow on my laptop (but KDE4 was also... underpowered laptop), but the solution for that which works for me is LXQt with Kwin5. It allows me to get the niceness of the new KWin without all the bells and whistles my poor laptop doesn't have the power to take advantage of. I'll reserve the Plasma razzle/dazzle for my Desktop.

Thanks again everyone for the hard work. It is much appreciated
