Are you unemployed or work nights? 8AM to me is considered sleeping in late. I have to get up at 5AM in order to get to work at 6AM for my job. Luckily I have off tomorrow so I can mess around with it all day and get it setup.
I think if you get there at 7:40AM it will be safe... every article states how the supply is plentiful and going to Best Buy is more low key than an Apple Store. But the Apple Store will have the biggest supply obviously....so it's a catch 22 situation.
I might stay awake until 3AM just to see if apple.com does in store pickups. Then I can relax and go later in the day to grab it. Plus the Apple store is in the mall here literally around the corner. Slightly closer than Best Buy.
I'm also going for the 128GB model which is the easiest to get as it's the most expensive. That's my thinking at least.
I'm a college student. I sleep in. Duh! Haha.
