So I've just sold my 21.5 inches mid 2011 iMac to replace it with a Macbook Air. But now,I'm getting hesitant as there might be a new Macbook Air coming very soon,I've been without a real computer for a week now and currently solely relying on my iPad Air.(which has it's limitations compared to a real computer). What do you think? Should I buy it? Do you think a new Macbook Air (likely with Retina display) will arrive in the next few months? I remember when I bought the iMac in summer of 2012 it was the latest model but I was kinda bummed when they released the re-designed iMacs couple of months after my purchase,so I'd like to avoid that bitter experience.
