It just now occurs to me that Marvel may have miscalculated by tieing their digital comics launch in with the launch of the iPad. What's the bigger news that day? iPad or "oh, look, Iron Man!" Of course, it seems to have fit neatly with the release of the Iron Man movie, but people are buzzing about DC's efforts as if we hadn't already seen Marvel pull this off already, and Boom! make an announcement just last week.
That said, I was discussing iPads with my boss, and I think I am waiting for the HP Slate and whatever Dell produces. Not just to be contrarian, but I like to look at YouTube and stuff.
