Thanks for all replys.

Some more questions:

Is there anything known about where the GarnetVM is heading.
Evidently if you cannot run a lot of commercial apps that is severe limitation - but then at the moment it is only beta - will this improve?
Can the Palm-apps that run in the GarnetVM see the SD-card?
And can the GarnetVM run in the screen-format that the T5/TX Palms have?

Could you please point me to some screenshots that show pdf-reading on the N800?

One concern for me is that it seems the N800 seems to be considerably larger and heavier (are there any pictures that show a N800 and a TX side by side?). I need something that I can carry around anywhere at any time and that would allow me to read ebooks comfortably while e.g. travelling. Is the N800 a good device for that or do you basically need a table to support it when you want to use it for a longer period of time because it gets too heavy?

Many thanks!
