Toshiba recently released a refresh of the Tecra line of Tablet PCs with the M7 and it looks like a refresh of the Satellite R15 isn’t far behind. TabletPCReviewSpot links to a manual for the Satelliete R20/25 that certainly seems to indicate things are close. That said, a tour of the Product Pages of the Satellite R20/25 reveals a Flash Product Tour but no detailed specs are posted as of this writing.
Once the R20/25 comes on-line, Toshiba will have refreshed each of its Tablet PC lines, Portege, Tecra, and Satellite. Both the Tecra and the Satellite refrehes have widescreen technology.
