    I have an old faithful first gen MBA (1.6/80GB) running Leopard 10.5.8 as my bedside Mac. Unfortunately I am spending more time at the beach lately and not enjoying the scenery, just lots of spinning beach balls. :) Seems the latest anti-malware stuff has really slowed it down.

    What OSX is fastest for light Word/Excel and Firefox use?

    - Leopard - currently installed, may just rebuild to speed up
    - Snow Leopard - had this on before. Didn't seem much better
    - Lion - no features I need

    Ditch 3rd party anti-malware software and update to 10.6.8 with built in anti-malware protection.

    Snow Leopard I imagine. What an OS that was, slapped it on my old 07 2.16ghz white macbook that I gave to my parents, runs like a charm.
