Subsidized-on-contract netbooks aren't uncommon in Europe, but they're a rarity stateside. Now, as rumored, AT&T's probably going to sell more Acer Aspire Ones. Costco training materials point to the 10.1" model, available from May 11th.
The leak may have come from Costco, but it's reasonable to assume that you'll be able to pick up the notebook from AT&T directly. There are no pricing details in the report, but the $99 precedent set by AT&T's last foray into on-contract netbooking doesn't seem unrealistic. [BGR]
