HP.com has their Compaq Presario C700T Notebook for $479.99 after a $200 instant rebate. Click on "Customize and Buy" to get started. I'd recommend upgrading to Windows Vista Home Premium ($29) and 1gb of memory (currently a free upgrade). It also has a 1.73ghz Intel Dual-Core Processor, 80gb hard drive, DVD / CD burner, wireless networking, and Windows Vista Home Basic. Shipping adds $49; tax is charged in most states.
