AT&T is to partner with Radio Shack for a new 3G netbook offering, in which the US electronics retailer will begin carrying the Acer Aspire device in its stores at a cost of $100.

In exchange, users will have to sign up for a two-year 3G data contract with AT&T. Without the contract, the Aspire One would sell for $350. The promotion is set to run in the US from 14 December until Christmas Eve.

The companies hope that the deal will further speed up the adoption of netbooks, which use wireless broadband networks for web and data connections. If successful, the programme could signal a new trend in netbook services and sales.

US telcos and retailers have long offered subsidised mobile phone deals with service contracts, but the tactic has yet to catch on in the burgeoning netbook market.

"Many people internationally are already enjoying the portability, on-the-go connectivity and affordability of this emerging new technology," said Radio Shack executive vice president of merchandising Peter Whitsett.

"Helping people stay connected during these challenging economic times illustrates our continued commitment to meeting their personal technology needs affordably."
