In love with the Surface pen? You're not the only one. Microsoft confirmed on its Surface blog this morning that it acquired the pen-sensing technology that helps power the Surface Pro 3 from the company that created it, Israeli tech outfit N-trig. If you're the type who pays attention to Israeli business newspapers, this whole thing might not come as a shock - Calcalist reported earlier this year that Microsoft was eyeing N-trig for a full-on acquisition that would see the company's 190 employees folded into the Microsoft mothership at some point. That's not the case anymore, though: We've been able to confirm the folks in Redmond just bought the technology, and not the whole company.
