When I was a kid I thought it was the coolest thing that Dick Tracy could call people on his watch and see them on the tiny TV screen, and I thought it would be awesome if, some day far in future, I could have a watch like that that really worked.
I was reminded of that today by XKCD.com:
Yeah, I can talk to people on video from a device I carry in my pocket – that is awesome. But it’s even cooler that Dick Tracy couldn’t play Angry Birds.
2022-03-12 Update: Eleven years later, now I can talk to my watch. I am Dick Tracy.
