I took the plunge and updated, so far it's running great for me! Memory usage seams to be about the same, tablet feels a tad faster (could be my imagination). On first boot it was using a lot of ram, turned off, booted into recovery and wiped cache, and rebooted. After that ram usage was pretty much the same on my device as it was with 4.2.2.
