Lol not really a revolution. Points which make it not revolutionary.

It's a proprietary format using pre existing tech (which reads like dell doing half the work to try and lock consumers and manufacturers into some long haul royalty bs).

It doesn't have a fixed size format (varies based on capacity).

Being faster than the previous gen when increases in perf are the norm isn't revolutionary. If anything because the tech is proprietary and just an amalgamation of pre existing stuff it's a step backwards.

2/5 for dell, they could have done better.

It's unclear from the article but this still just standard DDR right? Just a different connector? Honestly ultrabook vendors should just start soldering memory if thickness really is an issue. I'm an embedded dev and know many other developers. And I know of no one who ever upgraded their laptop RAM. CPU RAM is almost never the limiting factor nowadays anyway.

They already do that

And I know of no one who ever upgraded their laptop RAM

That doesn't mean those people doesn't exists. Actually I recently bought a 8GB SO-DIMM module so I can have a little more breathing room. After I replace the module I owuld have 12Gb RAM. If I could replace both modules I would did it, but 1 IS soldered 4Gb module and I can do nothing with it. An I have T440 sitting next to me which was upgraded to 8Gb because it's default 4Gb is not... much usable in 2022, along with 5400RPM HDD, which of course was replaced to SSD too.

EDIT:

Standard DDR chips. It's a different connector which allows for a faster modules to be used, because a current SO-DIMM has too much too long lanes which are very succeptible for interference:

> More specifically, RAM speeds greater than 6400 MT/s are not possible with the current standard. This ceiling is becoming a problem on very high-end laptops and workstations while most consumer-level laptops have yet to reach the limit. Naturally, more laptops will hit the ceiling in the years to come as RAM speeds become faster and faster.
> It’s worth noting that CAMM utilizes the same DRAM ICs as found on SODIMM modules but with a different interface to the PCB. Thus, it is this interface that makes CAMM special and the heart of the patents under Dell.

Sure they definitely exist. But I would be surprised it's more then a hundredth to a tenth of a percent of users. Sure you can pander to those, and you should if it doesn't have serious drawbacks. But not being able make laptops smaller is a serious drawback, even this CAMM memory is still stacking PCBs which costs quite a bit of room.
