If by 'Windows Tax' you mean that we can also run the ARM version of Windows 10 virtually, sure?
As for the TBW issue, when this first started to gain attention I noticed on Feb 23 my TBW was at 22.7 TB, which seems like a LOT! Looking today I'm at 24.0 TB. I've been keeping track almost daily and haven't changed my workflow. I do a lot of recording in Logic Pro X and some light editing in FCPX.. I've had a few issues with some 3rd party app compatibility, but most of those issues have been addressed save for a few non-showstopper type of bugs. Seems more like my iPad Pro 11in was the beta test for this M1 MBP.. IMO.
