I've been reading a lot of books on my ipod touch lately, but want a bigger screen now.

So which e-book reader do you recommend? (Kindle is the most famous one, but I don't know which type of Kindle is better).

I have the Kindle Fire and I like it, although I haven't actually used it for books yet. I mostly use it for internet for random web surfing and for apps. So, depending on your budget and if you want to use it for anything more than books there are a lot of options.

Here's a link that compares them and can take you to a review: http://ebook-reader-review.toptenreviews.com/

I hope this helps, since I can't personally recommend anything.

Depend what you read.

If you read book (text on white).
e-screen ereader
Kindle touch, kobo touch

If you read manga (graphic).
7 inch tablet
Nexus 7, kindle fire

If you read comic and technical documentation.
10 inch tablet
Asus transformer.

Depend also for how long you want to read.

I have a kobo vox 7 inch (less powerful kindle fire) for manga and book and it's a great, the screen is good, I can even read it under full sun.

I just read ebooks, so are there a lot of advantages with a Kindle DX vs. Kindle Touch?
