I see this "the iPad is too heavy to comfortably read" comment a lot. I have had an iPad v1 for all of 5 days, but in that time I have read more "long-form" material than the previous five months.
Too heavy? C'mon, really? Yes, it's heavier than a Nook. But to say the iPad is useless is hyperbole at best and misleading at worst.
It may depend on the amount of RSI damage your hands have taken. I've played with iPads at the Apple Store, and I can't hold it comfortably for more than a few minutes.
By comparison, I can hold my 6" Sony Reader (or the Nook Color I had for a few days) indefinitely.
And, yes, I do realize that the iPad is heavy for good reason: it's got a bleeping big battery.
And if you owned a Kindle you'd know exactly what people mean.
The iPad is heavy for one handed use, not to mention bulky. It does excel at PDF use though. To each his own. I prefer the Kindle for anything that is just words. Anything else is a toss up between iPad and nOok.
