Plastic feels cheap and shoddy. Macbooks (and such laptops) feel premium, and I want a premium product. I don't care about the price for a device I live with and work on daily.

The weight doesn't bother me, and in fact I _prefer_ it having some body to it.

Regarding impact... my 2015MBP doesn't look a day old. It's tanked hits that would break other laptops.
