Questions before buying M92

Hi everyone,

I'm thinking of buying an M92, but haven't decided yet. I have a Notion Ink Adam tablet with Pixel Qi screen which I find adequate for my purposes. I'm only interested in the M92 as a backup and a novelty. So I can afford to wait for something that fits my expectations.

I search the forums, but not very clear about the answers to the following questions ( mostly because of the deluge of the technical terms used in the forum :o ) . It would be great if you guys can help me out.

1.) If I understand correctly, the M92 cannot save pdf annotation notes directly on to the pdf. Is this likely to be improved in the future? In the Adam, I can directly annotate the pdf with the Android version of the Adobe Reader, and after I transfer it to my computer all the annotations including notes will still be there.

2.) I also understand that djvu files can't be searched for text in the M92. Is this likely to be improved?

3.) Sometimes I need to check something in Wikipedia when I'm reading. I know that the M92 doesn't support multitasking. But if I exit the pdf reader and turn the web browser on, can I get to the same page in the pdf as before easily?

Thanks!
