For multiple reasons: [Rant mode on] No longer my multiple magsafe2 adapters will work. BTW, the magnetic connection have been one great feature, that I'm also very sad to lose if I upgrade. I even bought a magsafe to magsafe2 adapter, so I can travel with my daughter's charger, and use it in both MBPs. Well, that's not going to happen anymore. What should I do with my thunderbolt cables and dock? I'll have to buy a new one, don't I? I use the SD card reader every day, I'm a photographer. So, I'll now have to use an external USB reader, but wait, I can't use it directly, I'll have to use a USB-C to USB adapter, and then the reader. Very cumbersome compared to what I do now, that is simply insert the card in the slot. Boom. And for those using SD card memory upgrades, they are out of luck as well. What should I do with my thunderbolt to VGA, or DVI adapters? They won't work either. And I can't hook it directly to the company projectors, I'll have to run around with an adapter too, like all the Windows users do. They'll laugh at me very hard [Rant mode off] Other than that, I like the design, the keyboard looks great and the touchbar have great potential. So, did Apple officially got rid of the glowing apple sign? That's a bit sad, don't you think? I know it was a useless feature, but it was kind of a statement. Well, I can live with that. No biggie. Anyone else having the same issues?
