Yeah, the Wallstreets had upside-down logos.
Check out this ebay auction
Scroll down and view the second photo that is available, you'll see the powerbook on the left has it's case closed and the logo is right-side up, meaning it will be upside-down when the lid is up.
EDIT: I forgot to ask my question! I'm in the market for an iPod and am an avid cyclist, both road/path and mountain. Do the iPod's skip much, or is one better than the other (mini/regular)? Thanks!
