Revisited: Linux Mint 16 "Petra" KDE + Xfce
After getting past the boot menu, I was greeted by the Linux Mint KDE (blue rather than green, and featuring the KDE gear under the Linux Mint leaf) logo fading in from black. The boot process was quite quick in leading to the desktop. The desktop doesn't have too many notable changes, so I won't dwell on those too much. What I will say is that the "Air" Plasma theme is flatter and whiter, perhaps in response to Microsoft Windows 8, but this doesn't go too well with the practically white desktop background. The other change is just that instead of having a separate folder view widget taking up part of the desktop, it has now been expanded to take up the entire desktop, making it look a little more traditional and less like stock KDE.
