True but again DRAM is still 10x faster at the moment so anything less than that at the moment would be a major downgrade. You'd need massive caches on the processor to make up for the slow XPoint hybrid storage. The computers would be moving like an early 2000s PC. Given the current cost per gb of XPoint it would still be too expensive. It'll need a few years to mature before it's ready for that.

Not really, its workload dependent.  Most consumer workloads would experience little to no performance degradation switching from DRAM to 3DXP but there are countless scenarios where there would be massive performance increase from switching from 4GB DRAM to 16-32GB of 3DXP in phones, for example.  Imagine truly instant on phones and apps never having to reload at all even when switching between numerous apps.
