So I am returning my defective MBP for a new one Monday, but have a concern for my replacement. I have had this computer for two days and the bottom already has a few scratches/scuffs. I've treated this thing perfectly, and cannot figure out how these scratches got their. Are the unibody MBP's really this susceptible to scratches? Will sliding a computer on a desk cause this, even though they have rubber feet? Will clear film help? Is it worth $50, or should I just deal with the inevitable? Thanks!
