To me it has to have a USB slot or a slot for an SD card. Somewhere to stick a memory card/stick. I don't want to carry another dongle around. Just so I can insert a little 1" card. They have to allow the ability to allow apps acces to documents on the mem card/stick. I hate having to open my MBP open iTunes add document to app and then go use it on an iOS device. Why not the ability to use the document from mem card/stick itself and this way I can go back and forth between iPad and mac easily without using iTunes. (Which I think may see a name change soon or a different app to connect and update devices.)
