As all our stuff is held in the cloud - which I dislike very much - less and less stuff we want to connect to our machine.
A few years back it was so annoying when they started to get rid of optical drives, but now nobody misses it. Soon we wont give a rats ass about USB as well. Especially on laptops, because on a desktop you will still need it for a few peripherals. But on a laptop where everything is built in...
My opinion is, that magsafe was awesome. I hate having everything in the cloud.
And yes, these guys will do whatever they want. Because 98% of their customer base don't give a damn and even if they do, they will still buy it, because of brand loyalty and other reasons.
