OQO appears to be set to announce an update to their Model 02 UMPC at CES 2009. The new Model 02+ will reportedly feature a faster 1.86GHz Intel Atom processor, an OLED touchscreen display, and worldwide 3G connectivity. The naming convention suggests that the form factor will be unchanged though.
With 2GB of RAM, the Model 02+ should also be twice as fast as the current Model 02.
OQO will formally announce the Model 02+ at CES 2009. Pricing should be revealed then.
