> bad choices

As one of them, no, not really.

I looked hard into the question but all the litterature I got was a mix of "I'll give you candy if you do X" experiments that beg the obvious "what if the kid doesn't want the candy for whatever reason ?", including their mood while doing the experiment. And this goes on for every detail of the experiments.

And the rest was philosophical and hypothetical "it's not like the olden days" style of conservatism, mixed with "this time it's different" to try to barrage criticism.

Testing on kids is just hard, so coming up with good experiments is in itself a PITA. I wish people would recognize that and take the research with shovels of salt (and I don't see misleading research as better than nothing).

Buying a kindle for my kid has been a decision that still pays dividends, I would have kicked myself if I refused it on social pressure.

Would you really compare a Kindle to a full fledged tablet with endless video and addictive games? I think you are being hard on yourself.
