I just got a MBP 13" and have some hardware questions. Is it better for me to put my MBP to sleep when I'm not using it during the day? Also what's better when I'm not using it? Should I leave the screen open or close it? I also want to use my MBP partly as a desktop computer. What stand is the best if I want to use the trackpad and normal keyboard or should I just buy a separate keyboard and mouse for use with a stand?
