I'm approaching 25 days. I just love this laptop. It's a maxed out 11"er. Code: my-MBA:/ me$ uptime 17:22 up 24 days, 23:09, 7 users, load averages: 0.50 0.50 0.49 Had to restart because of the updates. I'm using it more every day. Now it's (almost) my primary laptop. My use is mainly Outlook, Excel, Word 2011, web browsing, and lots open terminals.
