I don't want new promises, i want the old promises fullfilled.
If you want do academic reading none of e-ink devices are valid. You need an iPad in first place or other 9,7 Android tablet (but not cheaper Chinese ones).
By experience. I've used iRex DR1000, Kindle DX (and then DXG) and PocketBook 903... and none are valid (slow, a lot of bugs, inefficiencies, and you waste more time waiting while device perform actions than reading). Then, there is no reason M92 will be different from others.
Things go worse if you need to read more than one PDF and/or do intense annotation on them. For the last, even you won't be able to merge into PDF... and there is no reason M92 will be better for that than others I've own.
I had an iPad 1 and it was perfect for annotate with iAnnotatePDF and GoodReader. My iPad 3 is even better, with its Retina display fonts are shown better than in printed documents.
Multiple documents, a lot of ways to annotate, and for GoodReader you only need to configure cloud servers. You annotate, and then sync and your annotated pdf are in the cloud.
And one thing that no ebook reader has: speed. Document opening and browsing, zoom, page turning, scroll, etc. are almost completely immediate operations. And only one handicap: backlight.
