Apple released a stealth upgrade of the entry-level MacBook this morning. The white MacBook, still priced at $999USD, now has a 160GB hard drive, a 2.13GHz processor and a slight increase in RAM speed -- 2GB of 800MHz DDR2 SDRAM.

The previous version, released back in January, had a 2.0GHz processor with a 120GB hard drive and 2GB of 667MHz DDR2 SDRAM. Other features on the revised MacBook remain the same, including the NVIDIA GeForce 9400M graphics card that we wrote about a few months ago.

Thanks to all those who tipped us about this!
