Long-lasting. This 10.1 inch HP convertible is available for around 400 Euros. The manufacturer provides an Intel Cherry Trail processor and long battery life. A Type-C USB interface is also included.

This laptop seems like it is being discontinued, but I ordered one anyway because the specs are better than the Pavilion x2 10. Will there be problems, such as not receiving updates for drivers, etc? I have been looking for a modest 2-in-1 like this, so it would be a shame if I had to return it.
I just bought one on the Best Buy site. It was a black Monday sale. Paid $302 including tax Canadian. It's refurbished but it's guaranteed for one year. Hope this helps.
