Expensive devices turns to ewaste in shorter time frames for reasons other than support. This is a poor metric to pick on.
I agree with GP here. In the current security-obsessed zeitgeist, 2 years of security updates is criminally low, pretty much designed to generate e-waste.
(I'm an iPhone user, but just to point out that there are also more affordable options with longer support periods.)
As a counter though, I would say with 2gb of ram this device just won't be fast enough for most of its users in 3 years anyway; so although I find this a valid argument to make, a new issue pops up immediately (for me at least).
