After 30 years or so on a PC I moved to a Mac. I'm running Lion on a 2011 MBP. I upgraded to Lion with no trouble. My battery lasts long enough; 6-7 hours depending on what I do. I just upgraded to 10.7.3 and was back at work in about 25 minutes.
What am I doing wrong? It all works flawlessly they way it's supposed to
