Electronic shifting has been out for quite awhile. Wirelessly too. Though I'm not sold on being completely wireless. Too many batteries to deal with for each individual component. I'm already charging five or six other things I use on my bike. I don't need more. But it looks like when I get a new bike, I'm going to have to just learn to "deal with it".
You seem to be asking about the newer and lower cost stuff that's come on the market recently. Sure it probably works well when new. But will it last as long as Shimano or SRAM's electronic stuff does? That's still yet to be seen.
