CHICAGO (AP) ― There’s no makeshift memorial or candlelight vigil for Steve Jobs at the Apple Store in downtown Chicago. The tributes and condolences are in tweets and news alerts pulsing through the iPhones, iPads and laptop computers inside.

One customer visiting from Ireland says he heard the news of the Apple co-founder’s death when he saw an employee start to cry, and she told him Jobs had died.

At another Apple Store in Los Angeles, Joey Gonzalez was browsing with friends after finding out through his iPhone that Jobs had died. The 20-year-old said Jobs has shaped the way he listens to music and communicates.

Tributes came in from around the world. “iSad” was a trending topic on Twitter.

Mac Users Group Mexico released a statement sending its condolences. It concluded, “Let’s breathe deeply and say VIVA STEVE JOBS!”
