"This begs the question. WTF are people still buying laptops? The actual use case must be minute by now."
Everything's a compromise. Not everyone needs an all-out workstation, but many people do need something more than a smartphone to do their work. It's also rather silly to complain about laptops causing eyestrain and RSI, but then suggest that a 10" tablet would somehow be better; the only way anyone has managed to make a tablet that's actually useful for any work at all is by nailing a keyboard to it and pretending it's a laptop.
