Sadly, my Bubm iPad case developed a tear near the zipper and now often gets stuck zipping and unzipping (see photo). This is pretty disappointing after just a few months, and I do not put a lot of stress on it so it seems to be a quality issue.
I have not found anything else so perfectly sized for my needs. It exactly fits around the iPad Pro, holds my thin accessories in place and well organized, adds very little thickness and weight, and is just structured/sturdy enough to provide the casual protection I need for small falls or light rain. I hate to do this, but I'm going to reward their defect by buying a second one (just $9.94 on ebay).
On the bright side and relevant to this @waytools forum, the fact I'm willing to swallow my pride and order another is a testament to this overall concept of minimalist mobility with maximal capability that was inspired by having a Textblade.
p.s. I solved the Apple earbuds problem with a soft thin zip sleeve for them instead of Apple's hard case.
(update - when I went back to ebay I found out the replacement is $19.95 for the iPad size BUBM, not $9.94. In for a penny, in for a pound. )
