I have 2 in 1 device, toshiba satellite E45DW-C, I use it for laptop only not as tablet because I not comfort with keyboard in behind and my device so thick and weight.
There're plenty of 2 in 1's that are light and sexy, HP, Dell and Lenovo all have great choices.
For your question, since your laptop is good, go for a tablet!
HP Spectre x360 is totally light and beautiful~ Lenovo Yoga 910 as well. I'm still debating between a new surface and a spectre x360 - cant tell which way i'll go either
I would not want to ever use a "360" hinge device as a tablet. Too heavy and most of them too big. And the backward keyboard is just weird. The detachable is the only way I'd do this.
