Marvel Comics For Ipad

Is an iPad worth for Comic Books?
Guys, I live in a place that sell comic books( Comic books that are 40 pages) for $5, while in the US they are $2.99. I heard that iPad sells cheaper comics. So this is a great moment for me.
Now, the main question I am asking. Does the iPad offer a wide collection of comics?
Comic book fans understand that, every week DC and Marvel release comic books. All I want to ask do they sell Batman comics?Action Comics? Superman comics? All I want is Batman and Robin, Return of Bruce Wayne, Secret Six, Batman, Green Lantern and Superman. Do they atleast have those and release issues each week?
If that question was confusing, read this:
Here in the Middle East comic books are very expensive, as they sell them for 5 dollars. While in the USA, they sell comic books for 3 dollars. As you can see, our comic books are overpriced.
While iPad has comic books for $1.99. Now that is extremely cheap.
All I wanted to ask is, do they release recent comic books from DC and Marvel?
For reading purpose, the ebook readers are indeed better than multi-purpose device like iPad. It is more easy to our eyes with its e-ink screen, and it is specially designed for reading so it can give us a better touch and feel for reading.
For reading comic or manga books, you can consider the new Amazon Kindle. And as you may know, Amazon just released the new models of the Kindle reader (mine is Kindle 2, and now it upgrades to the Kindle 3 and sold at the same price). Here’s a fresh review about the new Kindle:

I’ve also mentioned quite a lot about the new Kindle, which model to choose and where to get free books, in another answer here:
