I have 2 bikes, one with a compact crank and 11-28 and the other with a 40T and 11-32. Living on Long Island, there's VERY few places the x1 will be difficulyh to get to.

I would consider this to almost be a "offensive" patent. Probably meant to be a roadblock to the other big manufacturers from developing something similar. I'm sure if SRAM could they would try to invent a 12-speed internal hub but Shimano patents probably prevent this.

I don't know. It's data point of one but I've some experience with and without triples. This spring I went from a 2007 Ultegra Triple to a 2020 Ultegra Di2. I was concerned I'd miss that low range on some climbs. But the 38 to 38 front to rear of the 2020 has me all good without the triple. Again, my experience is but one however, I am pleased with the switch.

If it adds expense and complexity, I guess we should look for it to become the new standard.

This is old news but Shimano has been developing a gearbox, according to one of their latest patents, the patent Sram had on wireless controls, will be redundant if the gearbox gets mainstream traction.
As far as range goes, a gearbox will beat any derailleur range available.

How does your flashlight or your electric car operate with dead batteries? Remember to charge them you say? OK, then an electric shifting works a lot better and that is why it grew from nothing to pretty much own the upper end of the business. This is the same with hydraulic disk brakes - you don't wear expensive light wheels out. Disks and new brake pads are cheap. While they aren't as large an improvement as electronic shifting, they are a definite improvement.
While I'm a little put off by SRAM with their multiple batteries vs. Di2 with a single battery, that is somewhat offset by the fact that you don't have to wire the SRAM - just bolt them on and they run. However, you only have to wire Di2 once per bike. You only have to charge the Di2 once every several weeks even under hard use.
