Not like this is that big of a deal -- but iLounge reviewed the 1GB
iPod nano, and while they find it to be pretty much the same gizmo as its more robust brethren (obviously), they do
point out one minor difference: the backlight doesn't seem to be as bright as the other nanos.
I can't confirm this and neither can Engadget, but c'mon: Would iLounge lie? Nahh.
If you have one of these nano-y doohickies and would care to share your observations, please post 'em in the comments!
