The 10.3″ is niche market in what is already a niche market. I can't imagine the Elipsa 2E sells well either. But both are far better than the reMarkable and the Scribe ecosystem is contrary to what Corporate users need, which is arguably the biggest segment of this niche. At least Sony & Fujitsu thought so.
The DX and DXG were total failures for Amazon, but the 9.7″ was too small and 150 dpi too low and HW too slow for Education & PDFs. Other issues too. i got a DXG in their last massive discount sale when they had been in warehouse for years. Still a waste of money.
The reMarkable and Elipsa was also a waste of money. The 8″ Sage does notes and PDFs better.
