This is what I posted on G+ today. While I'm not being a Sony apologist, they have really done well updates wise with the entire Z series line.
"Sony Xperia, I give you credit for the level of software support you've provided for the Z line since its launch. While we can argue the speediness of your software updates, you've managed to update the whole line for the past two years.
I am a Z3 + Z3 Tablet Compact owner. I have also owned phones abandoned by carriers within 4 months of being on sale. While the original Z and Z1 series owners are miffed as to why they may not get marshmallow, there are similar flagship lines who will never see 5.1.1 lollipop, even though their hardware can run the update.
If it means you can redirect resources to better manage other product lines, I'm fine with ending the Z and Z1 series at 5.1.1, provided they still get any critical security updates.
I hope that you're able to still provide the same length of support to the newer Z series models, even if you don't have a great sales year next year and are forced to switch strategy (which may include curtailing your portfolio)."
