>but as far as I'm concerned battery life is also irrelevant, and power consumption only matters to the extent that it increases my power bill. I use laptops because they're easy to carry around when closed

I'm somewhat in the same boat, but I sometimes use mine when traveling (without being plugged in), but fairly rarely.

However, another thing I really like about having a laptop is that my current one, at least, is very very quiet. Years and years of having a noisy desktop PC with loud fans really made me hate fan noise. With a modern laptop, I can do normal computing tasks and almost never hear the fan (and when I do, it's hard to hear), and I don't have to build some custom, non-portable liquid-cooled machine to get that.
