Soo. I just got my first mac, and I am calibrating the battery as apple's site says here (right now it is in sleep mode for 5 hours, i am kind of anxious though, i want to use it again tonight so it might be 2 hours for me, haha. On my pc right now). I was reading somewhere that it is bad to leave your laptop plugged in most of the time? I basically use my computer at home, and at work, and have it plugged in all the time at both places. Is this bad? What should I do instead? I don't know about the MBP, but on my windows laptop, photoshop, illustrator and After Effects (the three programs I use for work) run a good bit slower when the laptop isn't plugged in. So i dont know if unplugging my MBP every time it fills up, letting it drain down, and plugging it in again is a very realistic thing to do. Thanks for the help. I can't wait to get back on my MBP. 17inch, hi-res glossy!!!
