Yeah, the customs point is very interesting and worthy of upvote. I suspect they'd need a warrant to do this on an American (one would hope) but I highly doubt they'd need one to do this on anyone who ordered it from across the border.
Canadians (and Americans who talk to Canadians) in particular are probably highly vulnerable to this spying. Emailing Americans, calling Americans, ordering laptops from the US, etc. The NSA is probably free to tap/interdict all of those interactions without any kind of pre-approval or probable cause.
Bottom line: the NSA has done irreparable harm to global trust in dealing with the US(and, sadly, the US dealing with those outside their borders), be it communications or buying their products.
