With tech gear, there will always be something better in the future. The question is how long you want to wait. Given the readers that have been pre-announced or shown at CES, there hasn't been anything that has the DR800SG's 8.1" display, Wacom pen and portability for the US market.
But in another year or 1.5 years there will be color e-ink displays and other tempting things. Depends on how long you want to wait. Maybe Best Buy will have a sale
