Buying new Sony Xperia XZ2 Compact- released 2 years ago, bad idea?

I did something similar with an xperia something compact version a few years ago. The people at work looked at me funny when I ordered it ("but you can have the new shiny (and humongous) iphone???"). I'd still use it to this day had I not cracked the screen about a year ago. I'd have no issue with security updates but I would beware that eventually some apps may not work with old hardware - I don't auto-update apps so this wasn't a concern.


Edit: I had to google as it was bugging me that I couldn't think of the model, it was a Z3 compact, great phone, good battery and camera in a really good size handset.

Old hardware? It's more tha capable enough.
XZ2c has SD845, Z3c with SD801. Both are top tier SOC's, they are powerful enough for everyday usage.

If you are after a smaller sized phone like the XZ2c, you should get it, worry less about the software, the hardware has to be right.
