There's a line in the new Jay-Z song "Venus Vs. Mars" that says "Hove's a BlackBerry Bold, shorty is a Sidekick . . ." which got me thinking about couples that differ when it comes to tech love. There's no geek law that says you have to rock the same devices as your partner, but I've noticed most of my friends and their significant others share a common tech alliance (maybe it has something to do with the good old carrier family plan). Do you and your sweetie use the same type of computer or phone?
