I've seen goodreader recommended a few times. I payed for this app myself, and after using it...
I gotta think Mac users just don't really know what reflow means, or what kind of goodness they are missing out on. It's still the one area Android is winning.
If you know anything about coding do us a favor...go to the verizon store or best buy...pick up a galaxy tab and use the text reflow feature on the built-in thinkfree app.
Create that for ipad and charge me $10. I'll happily pay and recommend it to others.
(For those who haven't tried it...goodreader DOES have reflow...but it's super crappy, has no good options in reflow mode, switches to vertical scroll, and although it does reflow the text, it still, on resize extends the text beyond the screen area below...thus negating the ENTIRE purpose of using reflow in the first place. It makes me think of what someone might come up with if they had heard of text reflow, but never actually seen it and didn't spend much time trying to make sense of what they'd heard).
