WiFi-only Xoom headed to Staples for March 27th release?

If you're still holding out for a Motorola Xoom, here's some good news. The folks at Droid Life snagged a picture of a Staples ad depicting March 27th as the targeted release date for the slate. In addition, the tablet appears to be retailing for 600 bucks -- one the cheapest models money can buy. A Xoom, TI-Nspire and a new pack of pens, all from one place? Man, that really was easy.
