I've seen this floating around as well, and quite funny. The first few unboxing videos I saw from folks who attended the Google IO conference all ran into the same thing... and I especially love the one where the guy tries to open it with one of those plastic things you put in your collar. The first 5 minutes of the video were trying to get the tape off.
Yeah I"ll have a knife in hand when I go to open mine since I generally keep my boxes just in-case I sell the unit or need to send it back in for repairs.
