Impromptu Steve Jobs Memorial at The Mall in Columbia: 'iSad'

Fans mourning Steve Jobs' death have created a simple memorial at the at .

It's made up of notes pasted to the storefront with messages to Jobs.

The individual words vary, but just about all of them say the same thing: “Thank you.”

“He changed the whole world,” said Silvia Shatley of Odenton. “I just appreciate what he’s done.”

Shatley placed a bouquet of flowers at the store's entrance.

Jobs, the founder of Apple and its former CEO, at 56.

He started Apple in 1976 with childhood friend Steve Wozniak and together they created and marketed the world's first "personal computer," the Apple II.

Jobs had been ailing for some time. According to reports, in 2004, he publicly announced that he had pancreatic cancer. In 2009, Jobs received a liver transplant.

Messages pasted to the storefront included, “iThanks Steve, you changed the world, I hope you’re at peace @ your own iCloud.”

Another wrote: “Thanks Steve, words can’t describe who you are and what you did for the world, we will miss you.”

One message simply read, “iSad.”

Tim Hill, of Columbia, also stopped to read a few of the messages to Jobs.

He said he has been using his iPod for years when he works out. That device, he said, has made it so easy to take music with him while being active.

Hill said it has inspired him to work even harder.

“He was a great man and without that invention, we’d still be using primitive things like the Walkman,” he said.

Betty Powell lives in Silver Spring, but visits the Apple store in Columbia for classes on using her new Mac laptop.

She said she still remembers when she purchased her family’s first Apple computer in 1987 for $3,500.

She credited Jobs with creating products that were so user friendly that it didn’t matter if you were technically inclined.

“If he hadn’t been able to make it so easy, we never would have been able to figure it out," she said.

Tammi Rippeon, a nurse in Columbia, said she thought Jobs’ death was even more tragic because at the age of 56, he passed away before his time.

“It’s a sad day,” she said. “It’s sad for his family, for the business. He died too young."
