I have a new MBA 2011 and i still have 2 power adaptors for my old MBA 2009. Can I use the old adapters on my new MBA?
Acording to Apple you shouldn't:
Note: Adapters that shipped with the MacBook Air (Original), MacBook Air (Late 2008), and MacBook Air (Mid 2009) are not recommended for use with MacBook Air (Late 2010) models. When possible, use your computer's original adapter or a newer adapter.
