I feel I will be last one talking to myself.
So back to xps13, what I envision the use of ultrabook? To work on office documents, while multitask on web browser, email, and play some back ground music.
With this uses, I feel Dell make 16gb of ram available, the 256gb pcie ssd should be fast and adequate for it. The qhd+ screen makes text look clean and sharp. As for the touchscreen, perhaps Dell can put in a digitizer to use as note taking, as the standalone 13.3 touch screen is small and limited if it is for finger input only.
Dell can put in a finger print sensor on the screen too. The technology is coming and will alleviate the windows hello missing due to the low 720p webcam height limitation
