MacBook Airs and I have had a tenuous relationship for many years. I have had an original first generation Air (Early 2008) unit loaned to me for the last several years. Sometimes I’d use the machine a lot and sometimes not at all. My main issue (besides my lack of love for Apple) was that beyond the size/weight, it just wasn’t that amazing. Everything about the Air underwhelmed me. Sure it was light, but the screen was just okay, the battery was lackluster, the speaker sucked and it wasn’t powerful at all. Last week, I got my hands on the new 4th Generation MacBook Air (Mid 2011 model) and I’ll honestly say, my opinion (including my lack of love for Apple) has been changed.
