What does the USB-C equivalent of this [1] look like on a laptop with only one port? Apple basically killed the always-plugged-in peripheral with this revision, there's no way you could create something small enough that it wouldn't break in a bag that still provided pass-through for charging or other devices.

Do all monitors/printers/hard drives/etc provide pass through so you can charge? Or do you have to unplug your laptop from the power to get to your hard drive if you lose your dongle?

Not to mention the fact that every single mac apple peripheral you've ever owned is now worthless.

If they threw USB-C on as the charger alongside a USB and Thunderbolt I'd be stoked that mac is embracing new technology. If they put two or three USB-C ports and nothing else I'd be impressed with their commitment. With just one port, I'm left wondering what the hell they're thinking people use their laptops for.

I'm not sure why you'd want to use such a wireless mouse receiver with a computer that has bluetooth built in?

Also, I haven't plugged in a printer in years. Many printers have Wifi built in, and if not, you can always attach it to an Airport base station.

External storage? Use Apple's Time Capsule or any other NAS to back up your data wirelessly.

I've even seen companies use Apple TVs connected to a projector for wireless presentations.

Sure, a USB thumb drive is invaluable when you need to copy some files to your uncles 10 year old laptop with broken wifi; but you can get pretty far without wires if you want.

About 70% of the wireless mice on Newegg are not bluetooth mice. Non-bluetooth mice can have longer range or less lag for example.

So we are basically back to the old days of Daisy-chaining SCSI devices?

No, since they can all be connected to a single hub. This is way better than now, where you need one power cable, one, keyboard cable, etc.

What's wrong with USB hubs?

Want a legit answer? They lack power isolation. I had a device surge/short while attached to a USB hub (it was a branded one), and everything else attached died: Keyboard, Mouse, motherboard, and a phone.

This was back pre-USB 3, and the power limit of USB has only increased since then (USB 3, USB-C, etc). This means the wires get hotter, the hub gets hotter, and any short/surge will have an even more dramatic effect (e.g. fire?).

Honestly USB hubs should be up to the same spec as a surge-protector/multi-tap, but they aren't, even though they carry enough electricity to kill someone.

Nothing is wrong with hubs, but now there is yet one more thing you have to have available (at least until they become more prolific in external devices)

No, we will have wi-gig devices, most things will talk wirelessly.
