The built-in ATSC tuner adds just $20 to the netbook price, but there is a catch. You’ll need to upgrade from the 1.33 GHz Intel Atom Z520 CPU to the 1.6GHz Intel Atom Z530 CPU in order to purchase the TV tuner. And that’s a $50 upgrade.
In other words, if you were planning on paying for the faster processor anyway, the TV tuner upgrade is an excellent deal. If not, it’ll cost you $70.
