My single biggest fear was that they would end the MagSafe and that has come to pass. 3 kids, 3 cats, 2 dogs, the MagSafe has saved my existing MacBook Pro so many times.
Is it really that much to ask if one wants to use only official apple tech? One dedicated magsafe and this would have been a non issue. It can't have made the macbook thicker seeing as how small the magsafe is. They could have even mentioned in the keynote "and if you don't want to use the magsafe, charge your macbook from any of the usb-c devices" And simply put both charging options in the store so people could get a non magsafe usb-c is they wanted.
