I would urge caution with the XPS 2in1. The regular XPS13 are excellent though - my daily driver at work
We have two XPS 2in1 at work and both (competent) users complain of sluggish performance and issues with it recognising tablet mode etc.
I believe they have the ultra low power cpus and they just don’t seem to be up to the tasks.
If it was my money, for a 2in1 it would be either the Surface Pro or Surface Book, depending on budget.
The Surface Pro do have a few niggles from experience at work, but overall they are very good and work well as a tablet.
I like the look of the Spectre models, but HP always seem to change their models randomly so never quite sure what is current! There was supposed to be an OLED version, but this has mysteriously dissapeared from their own and retailers websites with no word of replacement.
