My guess is that there will be a few people there from around 6am , I'm planning on getting there for around 7am which I hope will give me a decent queue position. I was in the store yesterday and they are apparently going to be serving coffee/refreshments to people waiting .... don't know from what time or whether it will actually happen though.
Part of me wonders whether there will be much of a queue at all but I don't mind getting up early to make sure I get what I want 😀 ..... I was in Texas last week and visited one of the Apple stores there a few times to play with an iPad so I definitely know I want one and dont want to lose the opportunity this Friday and end up having to wait for the next batch to come in.
