I just recently bought a base model MacBook Pro (penryn) and I was just wondering when I close the lid of the laptop and put the machine to sleep, is it bad that I would put it in my InCase sleeve and move it/carry it around?Also when the laptop is off and still in the InCase sleeve, I usually have it in my book bag and have it placed when not on my back in a standing position (meaning the MBP is on its side).... is that something I shouldn't be doing if I want my Pro to last?
