Apple is a MOBILE DEVICES company. That's who they are, it's what they do.
The MacBook AIR isn't going anywhere. Why? Cause it's a MOBILE DEVICE.
Mindsets have to change, it's old to think that desktops of ANY kind reign anymore. 2010 and beyond is the years of mobility and these new Pro Laptops show that, the MacBook and MacBook Air are next.
Not to worry.
Aren't you contradicting yourself? Or do you mean with "its not going anywhere" that it is not going to be EOL'd - than I agree.
