Booxtor, one of Onyx's European retailers, posted this video on Youtube yesterday. As you can see in the video, the M92 is based on the 9.7" E-ink screen. Like the M90, this ebook reader also has Wifi, a Wacom touchscreen (hence the stylus), SD card slot, and it's running on an 800MHz Freescale CPU.
But there's also several major changes. The M92 has several hardware buttons and it's using a much improved firmware. I want you to look at the menus, and also look at where the various pop up windows appear. I think it looks fairly well designed, and this is what I expected to see on the M90 when I reviewed it.
The M92 is also significantly faster than the M90, but that goes without saying.
I was disappointed with the M90 because it was slow and because it was using the same menus as its 6" siblings. Now I see why. It's clear that Onyx abandoned their first large screen ereader and focused on the next model. That reinforces my opinion that the M90 isn't worth buying.
But the M92 might be, if not for the fact that Onyx is selling it for. It's scheduled to ship from Onyx on 8 December, and they are taking pre-orders now.
