This week’s iPad announcement generated a lot of buzz around the tech world — and while that launch is just a day or two old, some some folks are already thinking about what’s next. Mark Lowenstein, in his latest “Lens on Wireless” update says that despite the “15 screens” in the average home (PCs, TVs, phones, gameplayers, iPods) there’s still an opportunity for one more — “a hybrid PC/TV/entertainment device” that serves as a hub for family activities in the under-addressed kitchen (under-addressed for “screens” that is). First, the 15 screens took me by surprise, but it’s true — at least in my house. And I think this “family hub” makes great sense (in my brother’s home, the family PC is on the edge of the kitchen and we’re forever gathering around that small workspace — to play music, surf the web, view photos, check calendars). In the past, I’ve written about the personalization of technology — and the soon-to-be 16 screens in our homes are yet another example of this.
