When I'm working, I'm at my desk, with a keyboard, mouse, and monitors. But the reason why I have a light laptop instead of some beefy desktop computer is the convenience of having a computer when I'm not at my desk. At a café. Or to check emails when I'm at relatives'. Or to work on my hobby project in a car, waiting for my daughter to finish her training session. Or to be next to me, on a carpet, while I'm checking why the network under the TV is behaving strangely.
I've been living laptop life since 2002, IIRC. In all that time, the most stupid design decision I saw was on some HP EliteBook, where designers, in their infinite wisdom, put tiny legs on a laptop. Those four stupid pieces of plastic and rubber bite my legs every time when I try to use the convenience of having a mobile computer.
Fans on the bottom of the laptop case are firmly in the second place on my list. And no amount of ackchyually you're holding it wrong will change that.
