I got a Kensington Laptop Desktop USB as well. It was used for my Inspiron 8600 - but now will be used for my 600m. I got it on Ebay for $43.00 shipped, great deal considering it's around $80.00 before shipping through the company. I love it, unfortunately, the first month I had it, the 8600 accidentally scratched the inside (where the laptop is held in place) of Kensington Desktop holder. Still, I don't care -- the accessory is by far the best computer accessory I've purchased for my laptop.
