Re: Google's insistence on not learning from past mistakes...
Nobody wanted to lose an SD card slot, 3.5mm jack or removable battery. Keyboard, yes, that's very niche, but there would be buyers if there were offerings.
Many decisions have been taken in the pursuit of getting you to buy extra crap (new phone because your battery died, wireless headphones because you can't plug yours in any more, more storage at a higher cost upfront because you can't expand). Don't confuse those decisions with ones people actually want.
For the record my phone has a removable battery, 3.5mm jack and microSD slot (dedicated, can still run dual SIM alongside).. but that's not an easy combo to get these days.
