I mean I'm not sitting here defending soldered on ram but your unnecessary aggression and sarcasm in your previous responses overshadows the fact that while solder on ram sucks for the upgrade and repair market the underlying tech has very tangible improvements and now we can maintain that improvement and the upgrade and repair functions.

I agree, soldered ram is bad. But I disagree that LPDDR ram is fundamentally bad and this improvement allowing it to be modular while maintaining its improvements is a very good thing.

As far as your complaints of battery life on your thinpad goes, there is much more to battery life than the consumption of the memory but naturally every part plays a role and small improvements in multiple places result in a larger net improvement. I'm assuming you're running linux which in my experience has always suffered from less than optimal power usage. I'm far from an expert in that particular area but its always been my understanding that it is largely caused by insufficient fireware support.

As a whole this looking at this article in a vacuum i only see good things. A major flaw with lpddr has been address and i will be able to expect these improvements in future systems.
