The CEO of Nokia had to demo their latest handset one time on stage at whatever that big world cellphone expo is each year.

My biz partner and I wrote the demo that ran live on the handset (mostly a wrapper around a webview), but ran into issues getting it onto the servers for the final demo, so the whole thing was running off a janky old PC stuffed in a closet in my buddy's home office on his 2Mbit connection. With us sweating like pigs as we watched.

If you ever write up a more detailed recollection of that, I would love to read it lol
