You don't need to put easy debian on the internal, it's still good on a fast microSD card. (You need a miniSD adapter, they can be somewhat tricky.)

When I talked about the ebook reading properties, I forgot to say:
The n810 has WAY better idle time. Like, at least a week, probably several.

Although the browsers render web pages well on the N810, you don't want to open too many tabs. It'll hang.
