I personally wouldn't buy a very expensive android phone for the sole reason that in a year or two, the OS and overall look'n'feel will become "retro", old, and obsolete.
It's like owning the gold version of the 1998 Sony Ericsson phone for la creme de la creme persons.(

You wouldn't want to show it off today, would you?
I'd rather buy an expensive set of jewelry or a set of silverware as they come with a "timeless" look.
It's just my opinion.
Debate?
