To me, the greatest potential benefit of electronic shifting will be near-total freedom of form factor and location for the controls, including the option of having a fingertip/thumbtip control at each of the 5 or 6 grip positions on a standard set of drops. I presume there will be some sort of low battery indicator. Another cool feature would be a simple manual override, which would permit one to stop and to use a 4mm hex key to move the cage to a desired cog in the event of an electrical failure.

Wow, this kinda trick stuff amazes me, we went to a bicycle show on Sat. and they had a road race bike on a trainer, the guy was clicking gears but I couldn't find the shift lever's? Then I saw he was clicking a "black lever" which seems built in to the brake levers, are these what you guys call, bifters?? LOL, man I've been away from bicycles WAYYYYYY to long, it's like when someone is talking about a 10 speed, I invision a old Schwinn Varsity, their peaking of a 10 gear cluster
It's hell being a old guy

I watched the TOC on Versus and saw a bit of the hype...
What impressed me was the assertion that chain ring shifts
could be done under 'full' load.
It seems that I am always starting up the hill geared too high and
the ability to downshift using the front or rear derailleur under
heavy load would be a killer selling point for me.

They had the Shimano Di2 demo at the Handmade Bicycle Show in Indy this weekend. (I guess handmade bikes need the latest gear, too.)
The bike was on a trainer and they were inviting show goers to try it out.
As the chain was shifted from one end to the other on the cogs, the front derailleur moved slightly to keep it in trim. I didn't take a close look, but I suppose the front cage can be narrower since it is trimmed automatically.
They asked the test riders to stand and spin in the small chainring, then shift it to the big chainring while pedaling full speed. It shifted immediately under full load.
The front shifting ease seems to be the biggest improvement over cable shifting.

I have even switched some of my road bikes that came with indexed shifters back to friction. Why? Because I like it better. Any shortcomings of friction shifting do not come into play in my riding on those bikes. On the other hand, I really enjoy the indexed shifting on my SRAM X.9 equipped full suspension MTB. Things happen so fast on that bike that thinking about shifting would be a big problem and could cause a crash.But I have no problem with Shimano developing new technology. If it helps give racers an edge, good. If it gives rich people something to play with and to feel superior about, well so be it.
So long as they don't try to make me pay more for something that doesn't really make anything better for my riding experience or safety.
