Linus speaking Finnish

I'm a Finn and I've heard Linus in interviews on TV speaking Finnish. He's fluent, but his choice of words pretty quickly identifies him as having Swedish as his first language if you listen carefully. My first language is Finnish, but my place of work (in Finland) is primarily Swedish-speaking. In a place like this you inevitably develop an ear for the small peculiarities of usage that Swedish-speaking people tend to have when they speak Finnish, and Linus certainly has them.

Here's an old video of Linus responding in Finnish in a conference to a question (from an insane village idiot woman concerned about evil rays or something):
