The Sony Z3 Compact is a VERY powerful device, and also pretty expensive (U$ 400 or so). On slightly older or less powerful devices, Lollipop is INCREDIBLY bad.
It's so bad I'm recommending a switch to Windows for users that haven't bought into the ecosystem too much - basically U$ 100 Windows/Nokia phones outperform U$ 100 Android phones by a huge margin, so are a better buy for casual users, plus Microsoft is subsidizing phones over here.
My Google Nexus 7 tablet was unusable with the Lollipop update. My LG G3 Mini also performs extremely badly. OTOH my iPad 1st generation is still going strong (though I've seen iPhones go bricky with iOS updates).
Edit: note that I had badmouthed Windows phones previously after an incredibly frustrating experience with older Nokia phones.
