That was me that posted that the serial number was pulled off when I removed the old design. For some reason, the template for the 950 is different than the 350 and 650. For the 950 on the front, the skin doesn't cover the space above the buttons where the text is for back, forward, home, resize and options... the skin stops below the buttons so there's no need for a cutout area for the buttons. And on the back there's a rectangular cutout for the serial number label so it's not covered, it's fully visible.

On the 350 and 650 skin, you've got the text covered on the front by the skin (and the imprinted text is often fuzzy compared to the reader), and there's no cutout on the back for the serial number, the skin just covers it. I don't know why they did them differently. I often thought how much easier positioning the skin would be without having to worry about the button cutout.

If you check page 1 of this thread, you'll see the 950 up top and then others below to see the differences.

Edit: I spell like a putz when I'm tired!
