I used to say "the future is mobile," but it seems that time is now and possibly has been for a while; it will be interesting to watch laptoppers connecting. (will they request ethernet?)
I've been operating WiFi in my home for almost twenty years and only once has someone ever showed up with a laptop and asked to connect. Phones, and tablets to a much lesser degree, are taking over casual internet/email use, but no matter how portable they make "computers" I think there just isn't a lot of utility in mobility for demanding tasks that require horsepower and large/multiple monitors. A laptop with similar horsepower to my desktop costs about 4 times as much, so the desktop isn't going anywhere.
