Need advice on a tablet PC or e reader

[Drazzil]

I need something to browse the internet, read comic books and books (something that will read standard format books and comics) with no restrictions on the types of files it can read.

I read that the android and ipad file systems lock down the types of programs that can be used on their OS, so I am maybe looking at a cheap tablet PC?

Anyhow any advice would be appreciated.
