I was thinking about a dell. But the xps is expensive and doesn't fully fold into tablet form. And the inspiron has so so reviews. Shame as i wanted the on site warranty.
Possibly a lenovo 720 i7 13 or 15 inch then. Via John Lewis in tne november black sales.
Though it hurts spending 1000-1200 on electronics that have short warranties that involve sending away to get fixed. Especially when they typically have a failure rate of over 20%!
