Hi Mandy,

If you're not so computer savvy then the type of Digital Rights Management (DRM) that the device you choose supports will be a major consideration for you.

Any of the devices will read DRM-free books, such as those available from Project Gutenberg, but with the others your choice is:

a) Get the Kindle, and buy books from Amazon only.
b) Get one of the other devices and buy books from most other sites, but not Amazon.

The good news is that you'll be very happy with any of the devices. (Caveat: I don't know much about the Astak.)

You can do not-particulary-legal computer stuff and convert the books from one format to another, stripping the DRM, but my impression is that you wouldn't want to have to get involved in that. That mechanism is the only way you can use purchased books from Amazon on one of the other devices, or indeed purchased books from other stores on the Kindle.

Also, your forum name suggests you are in Australia, so check the extent of the Amazon support there if you do choose the Kindle.
