That would indeed be a bad argument. I'm glad I didn't try to make it. The iPad is a superb browsing/reading device. But sometimes people insist on using the wrong tool for the job. You want LaTeX on your iPad. But you don't have it and won't get it, because it's not a computer. That was my point. You want to take notes and use LaTeX? Why didn't you buy a used Thinkpad for $100 from ebay and install linux? That's what I did. I don't have the excellent iPad screen (or the battery life - I certainly see your point there), but I don't have to say "I wish this could run LaTeX / Gimp / gcc / python / ....".
