From BGR:
In other words a chance to get the Acer Aspire One for cheap. It better be, since they're going to bundle two-year AT&T 3G shackles with it!it looks like AT&T is about to start offering the Acer Aspire One 10.1″ netbook complete with integrated AT&T 3G access via a partnership with Costco. Costco employees are currently being trained for the launch and according to the info we received, the preparation comes to a head on May 8th. As for the netbook itself, it will become availble beginning May 11th. We’re pretty sure the Acers will be available from both AT&T retail stores and Costco electronics kiosks, just like Radio Shack’s current AT&T netbook.
