I'm excited about this, too, but I'm not going to hold my breath. I can't connect a bluetooth keyboard to my Lumia 920, or treat it as a USB mass storage device, or mount a thumb drive in its USB port, etc. Why should I believe they'll let me connect "future devices" to an external display? When I install Windows 10 on my phone, will I be able to remote desktop to it? Probably not.

You can since WP8.1 GDR2.

People can connect latest Lumias with Miracast support to external display for mirroring. Sadly, 920 is not one of them.

This will be supported on future devices according to this:

>treat it as a USB mass storage device

This will probably be never supported because implementing it will require disconnecting storage from phone's OS and MTP is supposed to be enough.

Edit: miracast is not supported on 920.

I wish I knew enough about Android USB to write a USB gadget driver that emulated FAT and Mass Storage - no reason it couldn't read/write sanely back to the host FS. Sure it wouldn't be as quick as native but it'd be enough to play MP3s on car stereos and the like.

They specifically called out the use of bluetooth keyboards and mice in the phone during their presentation, so that's a given. Since you're essentially running the full windows now, I don't see why remote desktop wouldn't work with the metro version currently present in their store either.
