I know they say a MBA can only have 4GB of ram but that isn't necessarily true. I had a Macbook (White) from Fall 2010 that claimed could only have 4GB of ram

  It is true. Check out the iFix it teardown[1]; you'll see the RAM is soldered to the board. I still don't think 4GB versus 8GB matters as much -- you'll be paging to an SSD, after all.

  Curious to hear how this was possible. You just put the RAM in? Did the Macbook recognize all 8GB?

  Ram is soldered to the motherboard on the new MBAs.

  The published maximum RAM is usually just the number of RAM slots multiplied by the largest module that exists for those slots at the time the machine is released. Frequently, larger modules are introduced later on, which the machine will handle even though it goes beyond those published specs. The MacBook Air is a different beast in this respect because it doesn't have any RAM slots. What you buy it with is what it has, forever, unless you're much more comfortable wielding a soldering iron than most people.
