How many people really use all of their ports? I don't doubt that most people here will use more than average, but I have two Mac Minis in my house for my family, and each uses:Few, if anyone, will want to give up ports (most of which are being used already) just to say their computer is round.
- USB 2 of 4: Backup drive + wired keyboard (with built-in hub)
- HDMI: Monitor
- Audio Out: Speakers
- Ethernet: Wired network
There's no indication they wouldn't either, all I'm saying is that they could; the machine does have Thunderbolt after all, which means an Ethernet adapter is easy to add. The Ethernet port is bigger than a Thunderbolt port after all, plus with Thunderbolt you can add more than just a wired network, if you prefer.Also, it seems quite doubtful at the moment that Apple will remove Ethernet from a desktop computer. So far there's been no indication they will do this.
While I personally use my wired network for nearly all of my desktops, I know plenty of people that are happy to just use wireless networks instead, and for people with lower performance requirements it's not a bad option.
All I'm saying is that Ethernet isn't a requirement, and neither is four USB ports really, and if Apple thinks they can come up with a great new design by dropping some ports then I'm pretty sure they'll do it. FireWire is doomed regardless, and the SD card is really just a novelty feature as it's not easy for most people to use.
It's not really important though; I showed in my horrible mock-up that you can actually compress the current set of ports considerably, which should be enough for a round profile, and definitely enough if they drop some more.
