I think the most obvious thing is that people claiming that Apple could make this battery removable have never seen/used a new unibody machine in person.

There's no reason Apple couldn't have put a second LCD onto ever notebook either. Think about it, they could just put some hinges on the current screen so the second one would flip out from behind.

There's also no reason they couldn't have put an OLED panel into the track pad to show the current time. Or a row of green LEDs along the palm rest area, one for HD read access, one for write, one for idle, one for WiFi availability, one for BlueTooth (though this one would be blue of course, duh!), a red one to indicate that caps lock isn't being used and a one that shines super bright white to let you know when your display is asleep.

If you can imagine, somewhere to the right of that would be a physical switch to turn on/off the wifi and and another for BT.

Personally, I'm glad they didn't.
