Look what quietly surfaced at IFA in Berlin. The folks at Engadget have spotted an unannounced Samsung Series 9 laptop with an ultra-high 2,560 x 1,440 pixel (221 ppi) display— that's a slightly higher pixel density than is found on the new MacBook Pro with Retina Display.

Samsung didn't officially roll out the laptop, and not much is known about it, including when it might see the light of day. But clearly the company is close on the heels of its archrival in Cupertino.
