Found a problem when trying to go for USB-C on Android.

I chose Mobile Phone to computer. It asked if I had an iPhone. I said no. It asked if I had an Android. I said yes. It showed me a picture of a Micro USB port and asked if the connection looked like that. I said no. Then it showed me a picture of an older iPhone with a 30pin connector and asked if I had that.

Can confirm. Dongle Daddy can't currently help me power my Nexus 5x.

Also, if my laptop doesn't have HDMI or VGA, I can't connect it to my TV. Don't some ultrabooks only have Display Port out?

Yes, and even if something has DisplayPort and VGA (like some Thinkpads) you'd probably want to use DP where possible.

EDIT: and I'm fairly sure the suggestion for connecting a VGA laptop to a HDMI TV doesn't actually work that way around.

Indeed -- many TVs have VGA ports, or DVA, and that should be the first option if the computer only has VGA (or DVA) out.

You can buy a VGA to HDMI adaptor, but I haven't tried one.

Not just ultrabooks, while my XPS 13 obviously only has a mini-DP my big chunky W540 from work only has one as well (the dock has one, but chances are consumers aren't going to buy a $150 dock for their TV when a $20 mini-DP to HDMI cable will do just fine).

Also... there are still people out there with phones that have the older Mini-USB socket.
