I think you're almost to the actual point -- they never finish what they start. You can be ahead of the curve, it just means your at the slow part of the ramp, but that doesn't mean you stop. It's a bit different, but if you think they're ahead of the curve (and I'm not sure I agree they are), they kill products because they haven't received a lot of market penetration. If with things like a lot of the software platorms they actual did more than (what I call) middle-third engineering, and did the last-third, perhaps it'd catch on more. Google Glass' issue wasn't it was so far ahead, it's just never been "correctly adjusted" to catch on yet. Despite the cool-factor there's no killer app for it. Apple does this, too, a bit far out, but they get buy in through partners and one or more killer apps for it, *including* third parties. The last bit is key, and they learned the hard way, but it's there now, even with unbelievably difficult industries like Apple Pay (which IM[Never]HO is much easier than the Record Labels must have been; bring on the Apple Pay lawsuits, too -- but as more evidence there wont be, at least not all that substantial).
