I keep mine on most of the day, I have it playing music most of the day. If I was to go downstairs or something I'd just close the lid. Of course when going to bed I turn it off completely.
i always make it a point to shut it down at the end of each day. the Mac deserves a rest the same way we do.
OT im practically a newbie and I find this thread really informative. I just got my MBP yesterday and I hope to learn more from this forum. Thanks guys
Before I used to keep my Macs on sleep and restarting once a month - never had a problem. Now all my personal Macs have SSDs so shut down and boot up is ridiculously quick - I don't even see the spinning wheel at the gray screen anymore. These days, I just shut my Macs down when not in use.
