With its plans to acquire Motorola's smartphone business and IBM's x86 server group, "it's almost a balance" when it comes to using the competing processor architectures, said Hortensius.
"We already do a huge amount of business with ARM, AMD, and Intel today, and we are quite comfortable with what they all offer."
However he was not bullish on ARM servers. He characterized them as "still an emerging trend more experimental than in any large deployments -- there are challenges anytime you are the new guy."
In tablets, Lenovo already makes both ARM-based Android systems and Windows-based x86 and ARM devices. "It's a mix, and we've had good success in both," he noted, although Lenovo ranks fourth in tablets behind Amazon and Asustek today.
Lenovo is the only PC maker with a significant business in both smartphones and tablets, Hortensius told us. However, more than three-quarters of the company's revenues still come from traditional desktops and notebooks (below).
Hortensius has been in the CTO role just 30 days. He has held a variety of positions since he came to Lenovo in 2005 with the acquisition of IBM's ThinkPad notebook group.
"I'll help do the work to make sure the big acquisitions close and, beyond that, find the elements of a tech strategy that is more than the sum of the parts," he said, noting cloud services will play a role tying the various systems together.
In servers, the IBM deal will give Lenovo the scale and design capabilities it needs to compete in the fast-growing datacenter segment. It already sells to China's big Web companies such as Baidu and TenCent.
