What misappear said.
As I noted up the page a bit, I'm a bit biased against "i" stuff, mainly because of what some of the computer mags have to say about them.
I think the performance of the free android app, PerfectViewer, is so good that it should swing it for you. And it has a free add-on for viewing comics in pdf format. Once added to PV it automatically, and very quickly, opens any pdf comic with none of the standard pdf reader gunge appearing. I'm just now looking at a pdf format comic and it displays exactly as a .cbz comic does.
I'm not sure just how much capacity I've used on the micro sd card in my tablet at the moment but I have so much to read on there, it'll be a while before I change it out for the next one.
I bought a couple of the publisher humble bundle offers and got a pile of tpb's and G.N.'s - some good Dark Horse stuff included - and I'm currently reading early, daily, Rip Kirby stories. I already have the Spanish language collections, which I bought in Palma, but my Spanish isn't that good, so the daily strip files are great for me.
Let us know what you decide on.
