You can tell Steve Jobs is long gone from Apple.  Why did Apple decide to not have at least one USB port?  This means I now have to buy a new wireless (bluetooth or USB-C) mouse and a USB to Thunderbolt3 adapter so all of my other USB devices can work.  I also have to buy a new portable hard drive since Time machine wants to reformat my entire drive on my current portable drive in order to be compatible with the new Time Machine format.  I can't do that since I have a lot of other data on it.  Also, there is no longer a magnetic charging port but instead now also uses a Thunderbolt 3 which is not as elegant and will likely break over time.  Definitely 2 steps backwards.  I haven't even gotten to see if it overheats since I haven't made it to the store to buy the new portable to transfer my data to the new machine.  Seriously thinking of sending this thing back.
