Tablets will not make any difference in this arena as they do the same basic things all computers do.
If that is your assumption I agree. It is true they do the same basic things all computers do.
But a lot of people wouldn't think of taking their laptops with them in the car and use them as navigation system. If you take the approach that a tablet is more like a PDA/smartphone, but it has a larger screen and you can do more stuff that you can do on a normal pc I think people DO think of using the tablet as navigation system in the car.
I would assume the requirement for nice software will increase as well. But hey...that is just my opinion!
The main difference is touch screen, not one of S&T strongest areas but not an area that will improve its real time navigation for all users. Also, page display mode which already benefits S&T as it reduces the wasted area at the bottom of the screen.

Yes, with regards to navigation
Streets & Trips may definitely improve! But there are also other programs like Mapfactor PC Navigator, Navigon NavigatoR etc that deliver TomTom alike navigation. Very good on the turn by turn navigation, but still a lot can be improved.
At least I really hope that a lot of software makers will see an opportunity here and start working on creating navigation software or improving the existing software.
For example, it would be nice if TomTom were to create a package for Windows 7!
