Considering that the whole thing has been compressed into an application on peoples phones and netbooks, nobody really wants to carry around an actual translator/pda/address book anymore. I suppose once the right technology comes around (i.e. special cooling systems and less than 20 nm technology with the newer biotech, non-silicon/semiconducter based stuff), PC's will become obsolete as well, and will be replaced by pretty blazing fast laptops. Who knows what the future holds, but the curiosity is certainly fun.
