Tribe I need help getting an ultrabook

Okay here is the situation.

My mother needs a new laptop for work.

Order of importance:

1- No more than $1000 after tax.

2- Good battery life so it must be haswell.

3- 13 inches.

4-Trackpad and keyboard need to be very good.

5- Good build quality.

So can you guys help me out I would really appreciate it.
