Are Electronic Comics Worth it?

I am thinking about subscribing to Marvel.com electronic comics. I am not sure if it is worth it or not. I like the idea of reading comics again. I love having physical comic books. There is something really good about being able to hold the book in your hands and the pages in your fingers. The problem is that Comic Books are really expensive. For the $5 a month for Marvel.com electronic comics I could afford one comic book and the gas to get to the comic book store.

I am just not sure it is worth it reading comics on my computer. If anyone out there has used Marvel's Electronic Comics let me know.
