So today Apple announced MacBook Air boasting 30days of standby and instant on. i was thinking hey, I can do that with my MacBook Pro 13' (April 2010 model) by not shutting down. Let it sleep, "instant on" when I wake the computer up. Then someone told me having MacBook Pro on standby for long period of time is not good for the computer.... is this true? I rarely shut down my computer. Only time I do is once a month or once in a two month to clean my Monitor.
