Have kids and/or pets run around in the same area where your computer is plugged in. Sooner or later one is going to tear on the cord - heck, even I do manage from time to time. And the connector looks so flimsy I'm afraid one time is all it's going to take. Nah, macsafe was the best invention ever in terms of charging.
so I have a reduced chance of incident occurrence, but if it does, it's probably fatal vs. a high chance of non-fatal incident. Bad trade if you ask me.
Judging by the coffee shop I'm in at the moment where about 1/3 of people have their machines plugged in, I don't think plugs are dead yet (not to mention at home or in offices, of course). Part of the problem is that the battery life is not yet at the level of phones. My 11" 2015 Macbook Air advertises a battery life of "up to" 9 hours web-browsing or 10 watching videos, but in practice I've found it closer to 6-7 while working actively, if I've got several apps open, wifi on, and screen brightness up. Maybe switching from Firefox to Safari would help, dunno (but I'm pretty tied to Firefox at the moment). I can get 10+ hrs on planes, but there I have the screen brightness turned down, wifi off, and am mostly working in a terminal vim.
Counter-point: As not-the-primary-computer, my MBA is plugged in 80% of the time and gets moved from place to place as my crowded workspace dictates. I can't count the number of times I've accidentally yanked the Magsafe connector out trying to move it just out of cable reach because I needed to get at something underneath.
Granted, a lot of that is learned behavior because I know I can yank the Magsafe out without incurring a $500 repair.
