What are you doing with yours? Mine comes in a few days and I want ideas.
Pi ideas
Kodi/emulator
I plan to use mine as a mediaplayer for my TV. Currently use it as a quake iii server
Seedbox
First thing I did with mine was fuck around with Scratch because it comes with Raspbian.
Then I set up an Apache web server with a self-certified certificate.
Then I bought a camera module (and new case) and set up a website with a time-delay image that looked out of my bedroom window that I could log in to (via ssl) and view on my phone.
Then I uninstalled all of that shit and put Kodi on it.
Emulating what?
How well can a Pi3 run 1080p videos? Will it be problematic?
Gateway for external entrance to home network via reverse ssh tunnel.
might wanna overclock it and make sure you have a 5V cord
I use mine as a torrent box. Usually let it run all night. Had a second one for Retropie but gave it away to a friend. I had planned to build a portable game console but the screen I got has such terrible latency that you can't play action games.
For the record I purchased an Adafruit 480x320 3.5" TFT, and it sounds like all of the smaller TFTs do not have the same latency issues; only the 3.5" has issues.
