Hello I just updated Lion on my MacBook Air (2011) and the only two things I can see changed is the Gatekeeper function and that my name is now in the top right corner of my screen. Could somebody tell me more about the latter? For instance can I make it go away (I'm use to the clock being the last thing on the top bar on the right side and I would really like it to stay that way). And also are there other changes I should be aware of? Sorry if there are obvious changes that I haven't seen. I'm still a newbie.
