The "reading" app should take care of that, just stick with ePub or mobi formats, plenty of apps to read them.

Google has data from devices that accessed Android Market:

Honeycomb accounts for 0.9% total (3.0 + 3.1).

I see many replies to this post arguing that this is a version 'for developing countries' and we don't need to worry about it.

Usual applications open: browser, mail client, im client (maybe more than one, like msn + skype), media player.

Why should a user from developing country be different?
