Re: pet tracker
"These might be 'must-have' devices for certain demographics, which I think is the entire point here."
Obviously, these devices are not something that anyone can find useful, but for those with the specific need they can be valuable. I can't care less for a pet tracker, for instance, because I don't have or plan to have a pet. However, when I read about it I immediately thought it will be great for many people I know who own pets. The same with all the rest. The only one that would be useful for me is the WiFi kettle with the iOS app for my tea. The garden thing sounds interesting, but I live in an apartment. And so on. :)
I would have liked to find one in the selection really useful for me, though.
Devices don't have to be conceived for everybody. :D
