I need a new computer. The last one met an unfortunate ending

I am looking for an ultrabook.
12-14" range
4 pounds or less without an extra battery
slice battery add on preferred
6 Gig ram
$1700 budget for computer and battery, chargers, etc. Docking station option would be nice.
I really like the rubberized bottom found on the bottom of beats edition computers.
My last computer was the ideal size at 8 inches wide and 12 or so long.
Thoughts?
Anyone bought a computer in the 6 months months and absolutely love it! Hate it?
