You can get one of those from System76. The 14" Lemur Ultra looks like what you may want, though I'm not really sure if that's an ultrabook. Their price is among the best (if not _the_ best). https://www.system76.com/laptops/model/lemur
I haven't heard of System76 before but their pricing is pretty competitive not to mention they claim to officially support a linux distro. Thanks for sharing :)
