Costco has updated their item page for the Motorola Xoom, changing the shipping date from April 1 to March 27. You can still preorder the Xoom and free gel skin case for $589.99 -- that's $10 off the MSRP and you get a free case. Costco also lets us know that you can walk right in to your local store and get one off the shelf come Sunday March 27 as well. Now that we've see what the competition has to offer from CTIA, are you still interested in the Wifi-only Xoom? Talk about it in the Xoom forums! [Costco] Thanks, Jon!
