The only time I find it less convenient is when I need to type text into an app that doesn't give me the option of enlarging the text. That's a pretty small part of my computer usage, however, so it's not a deal-breaker for me by any stretch.
The netbook doesn't handle video all that well, so I don't even use it for that. I have a Roku to stream Netflix, etc., and an external hard drive full of HD movies connected directly to the USB port on the HDTV. All that plus an HD cable box I almost never turn on. It's been working great for me.
This also speaks to the authors comment, "In addition, just because one scientist or study has evidence for something does not mean all scientists in their field agree." We have been told many times that "the science is settled" and that there is a consensus in the climatology field as to the facts of anthropomorphic global climate change. Yet the Climategate emails feature many, many examples of top climatologists expressing their strong discomfort with, and desire to be distanced from, such things as Mann's "hockey stick graph" and other IPCC publications, on the grounds that the science simply isn't there.
And when that fails to stop the flow of information, just have their homes raided and their blogs taken down...
