Just in time for Valentine's Day, HTC is offering the Nexus 9 at a deep discount. The US-only promotion, available until 11:59PM PT/2:59AM ET tonight, takes 40 percent off of Google's flagship tablet. That includes the 16GB, 32GB and 32GB with LTE models, which are priced at $239, $287 and $359, respectively, until the deal ends. Now, if you decide to go for the cellular version, HTC will throw in a free Logitech Bluetooth keyboard for good measure. You'll have to act fast, though, since supply for this Hot Deal is likely limited.
