I'm using Safari and I'm wondering if I should bother "updating Flash" as the home screen of Youtube suggests? I remember hearing people talk about older Airs running really hot with Flash and it draining the battery faster. Didn't previous MBA not even come with Flash installed? I'd rather not install if it I don't need it. I decided to start fresh with this machine, so no data carrying over from my old iMac. I plan on living light going forward, as I just started using Rdio and love it, so no iTunes really needed. Also plan on using cloud options for photo storage, etc. Any tips would be appreciated. Silly question, but how do I refresh a web page? F5 doesn't work, and I can't figure it out. It's pretty amazing having my first modern laptop, and this feels like the most modern laptop on the planet today.
