He's right. The pro's of a black plastic bag:

- It's cheap. Sometimes it's even free.
- No padding.
- Plastic stretches and ultimately breaks.
- There is a chance that you will obtain an RM 1400 paperweight whilst using it.
- No special pockets to store games/wires/controllers/anything.
- Offers minimal protection against outside forces.
- Worst way to carry a 360
