As expected to open​ the apps or the books Max Carta is slower than the 1st generation Max. Once opened, the page speed is almost the same.
300MB PDF took between 20-30s.
Why would we expect the new device to be slower to open a document?

Because of higher screen resolution with the same CPU

That's very good question.
Why would you expect the new May 2017 device come out with Android 4.0 and to pay €800? Crazy isn't it?

Everything is possible in Shenzhen.

Why on Earth would screen resolution affect the time taken to open a document? It'll affect (marginally) the time taken to render each page, but it shouldn't have any impact on the time taken to actually open it, other than a small increase in the time to render the first page shown.

Maybe it pre-renders the document, i don't know

If it does, that would be a poor strategy. A good PDF reader shouldn't take any longer to open a 1000-page document than a 1-page document; only the complexity of the page actually being displayed should impact times. It's a good idea to pre-render the following page while the user is reading a page; it would be a terrible idea to render every page at the time the document is opened!

That is generally right but I have seen PDF documents which needs several seconds for one page on a high speed PC.

The problem with the higher resolution is as far as I can see that there is no relevant hardware acceleration for the 'graphics card'. So the CPU needs to do that, too.

That means higher resolutions equals to slower page rendering.

I have a PocketBook 623 (about 1024x768 screen resolution) and a PocketBook 840 (1600x1200 resolution), and although the latter has a slightly faster CPU and more RAM, the former renders PDF pages much faster. I put it down to the lower screen resolution. This is just a guess, but every PDF rendering software I've seen uses floating-point math for rendering, and the ARM-based ereaders have to emulate that part of it. The more pixels to render, the more emulated math to do. I think these devices would be faster at rendering PDFs if there was software that used fixed-point rather than floating-point math.

We'll remain "Cartatonics" until the day arrives...

Nice. Would you like to write or record a small review for the device?

amen

You know what I reallly want? More storage. I would love 2 microSD slots or even more. I would pay a premium for more storage.
