or find your way about the board. and it really doesnt matter what kind of fretboard you have (maple, rosewood, ebony)..if its a quality guitar anyways...its really all preference.

I'd say the wood doesn't really matter as long as it looks good. But the inlays are mostly just fret numbering. Example, when you see a double dotted fret, you know it's the 12th fret (or the 24th if you have a 24 fret guitar).
