Re: Good design my a***
I had a Sony Vaio once that persistently failed to connect to WiFi. The power switch was a fancy sprung loaded slide to activate job that also released the clamshell lock. It was located right next to the WiFi /Airplane mode on/off slide switch which was about 2mm thick with a tactile surface. There was no Wi/Fi on/off light either, it was a green on-screen display.
Every time the user opened the clamshell, they clicked Airplane mode to on. I would go through a whole load of shitty superstitious mumbo jumbo removing drivers and adding them back and taking them away again and putting them back again... and then miraculously it would work. I had usually rested my thumb on the switch and pushed it back on by accident.
It took about 6 months and 6 visits from the professor in question before I eventually downloaded the manual and decided to read it page by page to see what was going on. Then, THEN, I noticed the little line with a number on the end pointed at the edge of the Vaio, and THEN I decided to look up what Number 7 was, and saw it was "Airplane Mode".
