I seem to recall mentioning that smartphones/PDA-phones would be the way forward a few years back. I wrote to TT on that very topic, and also publicly commented on their lack of support for TT6/Winmob users regarding map updates and software updates. I was told by some that it'd never happen.
Ahem. "I told you so!" (God, I enjoyed saying that, )
Anyway, the complete intransigence and arrogance to SP/PND users, in favour of their PND kit, led me to drop TomTom like a rock and move to other s/w solutions. I now use NavFree on my Android phone, when using satnav. It hasn't got all the functionality of TT, of course (no custom POI files, for example), but that'll come in due course, I suspect. It still does the navigation thing reasonably well, though.
TomTom only have themselves to blame, and I sincerely trust that the directors get bitten in the wallet by their justifiably angry shareholders.
Petard, hoist, their own, by. 'nuff said.
