Yes, I will.
Something I have noticed watching some youtube videos is that it appears the keyboard retains oils from your fingers and leaves smudges on the black keys, is that true for those that have the new keyboard? Or is it just the reflection in the videos? Is this an issue for anyone?
Finger oils on keys happen to just about everyone. You can wipe them down for awhile but it's going to get shiny after prolonged use. I wouldn't worry about it.
