Comics and Tablets: Your Thoughts?

I’ve recently become interested in reading comics again.  I used to read them as a youngin’, but sort of gave up on them for one reason or another (I used to collect all the trading cards from Marvel, too, and probably still have some floating around — there’s a box of comics somewhere in my closet).  But rather than jump in to whatever is going on right now, I want to read a lot of the backlist to get a sense of how things have progressed.  Understandably, that means doing so digitally (through the Marvel database, etc.), as trying to buy all those older comics would probably bankrupt me.

What I’m wondering is whether any of you have experience reading comics on any tablet.  I know there are a lot of different types out there, from the ASUS Transformer to the iPad to the Galaxy, but reviews can only go so far for me.  I need a bit more before I make that investment.

If you have read comics on a tablet, or at least have experience with one, let me know your thoughts about that particular device:  pros, cons, recommendations, etc.  I am partial to tablets that are connected to a vibrant app community, as reading comics will probably requiring the use of apps (PDF and CBR/CBZ readers).

Thanks!
