I'm specifically wondering what you would use TB3 for right now. As in, if the new iMac came out today? I'm trying to hold out for a new iMac while my 2010 Mac Pro is showing signs of slowing. I am excited for TB3, but looking around for accessories there isn't much out there. I'd like to buy a TB3 external drive array, but that product doesn't exist. So now I'm wondering if the whole TB3 port is even something I should worry/wait for. What products will you be using when you get a TB3 iMac?
