Not all the updates in Lion are huge, world-altering features, but for those switching from Windows to Mac, this one might make life a little easier. Apple appears to be dropping "Airport" from its preferred vocabulary, instead adopting the more widespread "Wi-Fi".
Wi-Fi has been the preferred term for wireless internet connectivity for most of the tech world , and, notably, iOS applications, for a long time, but AirPort has been Apple's name for the various 802.11 standards since 1999 when Steve Jobs introduced the first iBook with Wi-Fi capabilities.
The AirPort name has never really been used outside Apple, but the term Wi-Fi has become more and more popular over the years and it seems Apple has finally acquiesced to popular vernacular.
Thanks Oded!
