On his first day as Apple CEO, Tim Cook reassured Apple employees the company "is not going to change," according to an email obtained by Ars Technica.
Tim Cook took over as CEO after Steve Jobs resigned Wednesday night.
"Joining Apple was the best decision I've ever made and it's been the privilege of a lifetime to work for Apple and Steve for over 13 years," Cook wrote. "I share Steve's optimism for Apple's bright future."
Apple stock stumbled in the wake of Jobs's announcement, but by midday Thursday, it was down only about 1.3 percent from Wednesday's close.
"Steve built a company and culture that is unlike any other in the world and we are going to stay true to that — it is in our DNA," Cook wrote. "We are going to continue to make the best products in the world that delight our customers and make our employees incredibly proud of what they do."
