In fact, Lenovo's CEO Yang Yuanqing seems confident his company is going to wipe the floor with Microsoft. Speaking during an earnings call he explained:
"[They're] just one of our many competitors. We are still confident that we are providing much better hardware than our competitors including Microsoft."
That's in stark contrast to Acer's CEO, who's more than a little stressed about Surface:
"We have said [to Microsoft] think it over. Think twice. It will create a huge negative impact for the ecosystem and other brands may take a negative reaction. It is not something you are good at so please think twice."
