Sony's Xperia Z line up getting 5.1.1

I've got to hand it to Sony.  They haven't been too bad with the updates for their devices (I'd make a joke about how little their devices are out there that they have to worry about, but that'd be pretty petty of me).

But they've rolled out to their recent devices, and now are even rolling out to the older line up.  The Xperia Z is about 2.5 years old!

Here's the list of phones getting the 5.1.1 update:

Xperia Z (C6602, C6603)
Xperia ZL (C6503, C6506)
Xperia ZR (C5503)
Xperia Tablet Z (SGP311, SGP312, SGP321)
