How I miss my galaxy S3!

I'd hook it up to a proper display using an MHL cable then connect a Bluetooth keyboard. It was a sweet setup and the assorted tools (plus root shell) actually came in very handy. It could fill in for a laptop quite nicely.

These days it seems there's no legitimate alternative to MHL... can any phones directly connect to a display anymore via wire? Or is the only option screencasting to a smart TV?

FWIW, I generally like my appliances on the dumb (or open) side.
