I halfheartedly agree with OP, and I also halfheartedly agree with the last poster.

Getting outside and teaching your kids how to play with the real world is important, but removing ALL electronics is definitely just as much a detriment as removing all outside play.

A simple solution is to just not by frivolous electronic toys. Try getting them a breadboard and some wires and lights to play with; if they get a book on electronics and wiring they may find it quite fun, and it's definitely useful and educational. They may end up being electrical engineers if they get into it.

Some learning software and the such isn't bad, either. TBH, i think the best electronic investment is a decent PC. You can install pretty much any kind of software to do anything you want, and if you encourage them to learn about computers they can eventually get into building their own boxes and maybe want to get CS degrees or something.

Electronics teach us about the driving force behind advancement in the modern world; electricity and logic, as well as helping to possibly solidify the concepts of math and physics models.

If i never got a Lego Mindstorms kit when I was younger, I wouldn't have had the drive to learn about mechanics that inspired me to take Dynamics, Statics, and Mechanics classes in college. Same with Erector sets.

Modern toys that encourage creativity and critical thinking usually have some electronic component, so don't just write them all off as a waste of time.

Don't get consoles, though, unless your kids want to learn to hack and mod them. I never owned one and wasn't allowed to even have a game boy, and I see a lot of young adults who are pretty much stuck in the 'Gotta buy special editions, HALO RULES!' state... limiting their exposure is a good idea, but definitely don't eliminate it...

Just an opinion.
