by the time the battery wears out on this one, the speakers are also busted anyway (infact it already is true for mine). So battery replacement isn't an issue for me, the device will be worthless by the time I am done with it.

There is no proof that user-replaceable batteries meaningfully reduces e-waste. A lot of tech is upgraded due to obsolete CPUs, etc, not batteries. Plus, batteries last a long time now.

Also, landfills work really well. Most recycling doesn't work and pollutes more.
