I didn't have to attend the reveal event to watch it; I streamed it on a PC and took notes on a netbook. I talked to a friend about it on an iPhone. I participated in, processed and ultimately covered the announcements across three different screened devices, none of which was a television. Yet in Microsoft's world, the TV is still the core of the theoretical home for people who want "immersive worlds and epic battles".
My parents and their Boomer friends have those theoretical American homes, the kind with the spacious sofa and the dominant television altar, where they mainly watch on-demand recordings of cable shows. They don't want a game console. They don't want to talk to their television either. I've got friends who love immersive worlds and epic battles, sure. They have thousands of dollars in student debt and tiny, impermanent living spaces; their generation isn't exactly about to broadly become the next generation of home owners. We play games on consoles and we watch shows on television and we Skype and Tweet from laptops, netbooks, iPads, PCs.
