Windows RT tablets never managed to become very popular, but the new price tag of the Dell XPS 10, now just $300, raises a few questions.

While the Dell XPS 10 Windows RT tablet used to cost $499, the new price cut is widely seen as a new low for Windows RT. Everyone knew it was not faring well to begin with, but this just proves how bad it's actually doing.

The Dell XPS 10 is now available for $299.999 from Dell, sporting quite a substantial price cut. In terms of specs and features, the tablet is no loser. It packs a Qualcomm Snapdragon S4 processor clocked at 1.5GHz, a 10.1-inch screen with a resolution of 1,366 x 768 pixels, 10 hours of battery life, dual cameras - front and rear, a micro SD card slot for expandable storage, and 32GB of internal storage capacity. The Dell XPS 10 also includes Windows RT with Microsoft Office Home & Student 2013 RT.

While Dell might argue that the new price cut is just a promotional scheme, the discount may actually have something to do with the fact that Windows RT tablets are not exactly flying off the shelves. Even Microsoft's online store seems to be avoiding listing such tablets, as CNET points out. Except for the $499 Surface RT tablet, Microsoft's online store offers only few if any Windows RT tablets. Even Best Buy has a very limited stock of RT tablets, and it makes sense. If they're not in demand, why keep them around?

On the other hand, popular or not, Windows RT is not going anywhere. Speaking at the JP Morgan technology, Media, and Telecom Conference on Tuesday, May 14, Microsoft's Chief Marketing Officer Tami Reller said that Windows RT provides "much more flexibility," allowing the company to cover a broader range of mobile devices.

Back in March, Microsoft's Michael Angiulo also told CNET that future Windows RT devices will sport built-in 3G/ 4G, which means that more RT devices are on their way. The Dell XPS 10 Windows RT tablet is a higher-end model enjoying AT&T 4G LTE, but it seems customers were not exactly lining up to try out Windows RT. Will the new $300 price tag attract more customers?
