Well, I'm not one to obsess with the idea of new Zaurus "replacements". I purchased my Zaurus only a few weeks ago, fully aware that it was a discontinued product. I love my Z and it's in a league all of its own... . .
BUT, I'm definitely intrigued by this new thing that has just appeared on the JKKMobile Blogg. I have no idea who is manufacturing it or when it's due to arrive, but it looks very promising at first sight (well, from what you can see of it in the video).
If anyone comes across any further details on this, please post as I have not managed to find out anything else.
Here is the original JKKMobile News post which includes a short YouTube video video of the device's presentation.
