So I'll be considering the following:

Dell XPS13
HP Spectre x360
Samsung ATIV Book 9 Plus
Lenovo Yoga
ASUS Zenbook

So both Dell and HP I've tried in the past and it was pretty bad. I still have a Dell StudioXPS 16 from 2008 and it keeps on breaking down. I'm real skeptical however to give both Dell and HP a try again. I have never tried Samsung, Lenovo or ASUS. Hopefully some members have some recent firsthand accounts on the above brands.

Thanks
