A shop has a Di2 Prince here. The Di2 looks OK I guess but it still has the wires in place of shift cables. It seems like a bit of a gimmick to me, at least I would want a wireless version if someone was to fork out the $$.
As Verbs and Nouns says, battery charging all the time could be annoying.

In Ride 42 Rob Arnold tested Di2, the people at Shimano said that the battery would last about 2000km (thats a conservative esimate) and would eventually need to be replaced, but not until atleast 500 recharges. In regards to the wireless option, bluetooth was considered, but it required a transponder at each junction, which would add to much weight.

2000km is pretty good. No need to really worry about that then. They say in the reviews you can shift under power really easily too, even with the front derailleur.

Another step into low durability fantasy-land.
Change for the sake of change and profit.
It makes little sense to me to get something that works well without batteries and then add complexity and batteries. Why?

This stuff wouldn't bother me if I thought the technology wouldn't trickle down, but I know it likely eventually will. Then I'll have to start hording cable derailers, cables and shifters because all the modern quality-level components will be electronic and the cable stuff will become either boutique and expensive, or low end trash. Good examples are steel frame bikes and 7 speed rear.

And before you start thinking I'm just a retro-grouch, technophobe idiot, I've worked in a technology field for many years. Things are almost constantly changing, so we have a saying at work with each new "leading edge" development, "One step forward and two steps back".

Having said that, some developments are worthwhile, but many aren't and hope this one takes a long time to catch on.[/rant]

Kmow what you mean Nobody.

My workplace went to a computer based interlocking for train control replacing a century old electromechanical system about a year back. Millions spent, software version 2.48 at last check in 0.01 increments and the throughput is about 75% of the old stuff. At least another 6 months worth of debugging according to the tech who was headhunted after commissioning. Reliability? Well... There's less failures, but when they do there's no way of working around them. Call the techs and make a cuppa, nothin's moving.

Change is not necessarily progress.

why would one purchase a Italian made carbon fibre machine, and then proceed to insert a japanese fast wearing set of gears :P

Twice the price of Campy and then they even copied The casette, ramped cogs, pickup teeth on chainrings, combining shifter and brake lever + lots of other things.

Campagnolo FTW!!!

How are these better than a high quality mechanical system?

The precision of shifts is said to be much better. Multiple gear selectors for little added weight (eg, on the tribar).

In the longer run -- like when this sort of kit becomes available at a consumer price -- I think there are so many advantages that electronic shifting will become typical.

Self adjustment.
Wiring rather than cabling, solving a major cable routing issue (at the moment cables go under the frame and collect road grit).
Automatic avoidance of crossed chains.
Automated gear selection on the flat (to maintain cadence), upon starting from standstill (keep hands on bars).

And of course in consumer kit you can't forget bling. Which electronic kit sadly allows a lot more of.
