List of very high res, high PPI laptops (> 1080p screens)

We're just now getting a slew of very high res laptops with the release of Windows 8.1 which is continuing to improve on high PPI screens. Unfortunately, I haven't found a good list of high res laptops searching the Internet so I thought I'd compile a list and see if anyone else has any more to add. I'll try to update the OP as more info comes in.
