I've done a bit of development on a 7" tablet and it's kind of painful, even if you're using "just" a text editor (or an IDE like Eclipse with most of the chrome hidden). At some point you start hitting some physical limits of the human body. At 7" or 8" you can't have a full-size physical keyboard and there are only so many lines of code you can fit onto the screen, and so forth. Personally (and I do mean this is personal preference and not the One Right Solution For Everybody) carrying around a 3-5lb notebook isn't a big deal because I'm already going to be carrying pen, paper, a few medications, and a charger or two. Even if my main computing device weighed zero pounds I'd still be carrying a small bag.
