    Quick question for those of you that have MBAs. I have a 1.8 80G.
    I charged my battery last night over night with the comp sleeping.
    Before work this am i unplugged it b/c light was green and let it sleep all day. (never opened it)
    When i opened now, at suppertime, there is only 90% battery left. Is this normal?
    (8 cycles / health 97-98%)

    Sounds like it's normal. There is battery used keeping the contents of RAM alive even during sleep. I think a rule of thumb is about 1% per hour so it sounds normal. If the computer was shutdown instead of sleep you should be at 100%.

    The good side of the grass.
    Yepp, looks like mine anyway - normal, who knows?? The Airs do seem to eat a bit more battery when in sleep mode than my MB or MBP do.
