Cheap $300 basic Lenovo G50

has 2515 score cpu, 6GB RAM, 500GB HDD, basic 15.6 size about 4.6 pounds. DVDRW

Acer at $400 after rebate is cheapest i5-5200U available. Well featured, but like HP and Dell, Acer is not great reliability. Still full featured at $400 can't be beat

i5-5200U 3523, 8gb 1tb touchscreen 6 pounds big battery

Business level $440 http://www.adorama.com/...09TUS.html
T440 has higher reliability record. 4 pounds, i3-4030U 2708 score 4gb ram, 500gb 7200rpm, extra features.
When thinking Macbook air, Thinkpads have a good history. This is a beautiful business level with lots of extras. Not as fast as the Acer.

$480 Thinkpad L440 has no webcam, but model number shows 3 year warranty

Like the T440, business level. Weighs 5 pounds. 1400x900 resolution screen, fastest i5-4300M 4426 score, 8GB RAM dvdrw
This is a nice balance also. It is thicker than the T440, no cam, but offers a higher resolution speed and fastest cpu of the bunch. The CPU is 66% faster than the MacAir. Should be sturdy against drops and liquid spill.

You have to decide which of these is best in appearance. The Thinkpads have good keyboards.
I did not find any better for the price. These are each very well priced for what they offer you.
There are free video editors

You should not need to go higher in price than these.
