With this, an official 64-bit OS and the ability to boot from an external (much more reliable) drive, the Pi is looking more and more viable as a full-time entry-level desktop machine.
At this point, I think the only thing holding it back are the CPU and associated thermals - it is still slower than low-end Intel chips, but not by much, and it is interesting to consider that the price point is now moving into Z83ii territory.
(A 4GB RAM/64GB EMMC Atom x5-Z8350 retails for $150, and you get moderately decent storage, a PSU and a Windows license for that price)
