OWC said that the company is offering an improved version of the tablet in time for the MacWorld 2008 show, which opens today. The upgrades include built-in GPS, which includes the Wide Area Augmentation System (WAAS) for improved accuracy.

The OWC-Axiotron Modbook comes in two flavors. The cheaper $2,279 model includes a 2.0-GHz Core 2 Duo chip and a 80-Gbyte, 5,400-RPM hard drive and a CD-RW/DVD-ROM combo drive. The slightly more expensive $2,479 model includes a 2.2-GHz Core 2 Duo chip and a 120-Gbyte hard drive, plus a double-layer SuperDrive.

The Modbook is better than ever today, benefiting from the latest, higher performance Apple MacBook base platform - Apple Leopard 10.5 OS - and new Axiotron Modbook Tablet features including standard inclusion of built in GPS.
