    What does a matched pair mean?
    2gb + 2gb

    mixed = 2gb + 1gb ??

    OR does it mean a matched pair is the same size, from the same mfg?

    I have 2 gigs on my iMac, should I buy 2gb more from crucial OR buy 4gb and 'toss' the 2gb that came with it?

    In front of my MacBook Pro
    Mixed is (for example) 2 Gb + 1 Gb where matched (for example) is 2 Gb + 2 Gb. Manufacturer doesn't matter as long as the chips are the same spec it will count as matched. For most people, 2 Gb is enough, but if you are editing HD videos in iMovie or something on the more intensive side of computing, 4 Gb would add a little speed.
