I'm using an HP Envy with a fifteen inch touchscreen, running Windows 10, and it's great. I use it with a mouse and keyboard during the day (I'm a software developer), then use it as a TV in the evening, when the touchscreen comes into its own. I'd recommend you get something with a hybrid SSD /HDD, or if you can afford it a full SSD. Everything is so much quicker. I've the hybrid drive, and full shutdown to back to the desktop is about 45 seconds.
