The Sage is limited by the screen performance, so doesn't need more CPU.
They need to ditch all those magnets (4, 6, 8?), the power cover port and have a larger battery.
Also make the page turn buttons more reliable. It's maybe a SW issue, but the original Libra is fine. I can't use the Sage to record narration. The original Libra is good.

There is nothing wrong with contrast. It only needs a newer eink panel if it's faster whole page refresh and faster part update for notes. They also need to have more of the Nebo iOS/Android features such as keyboard support and PDF annotation with converted text and copy/paste that works between epub / notebooks/ PDF annotation etc. It's like three gadgets, not not one.
