I am really excited to buy my first iPad on friday. I know that the apple stores are starting to sell the iPads at 5 pm. I was wondering what time I should show up to stand in line. I am currently on vacation in baltimore and the apple store is just a couple of minutes walking distance from me. What kind of lines do I need to prepare for? If you are in the same boat as me, what is your plan for friday?? Thanks for your help.
