I'm about to buy another TomTom Go device; I have the TomTom Go 910 now.

The benefits of upgrading to a newer version of the device often appear to be that they can handle new features.

For example, over the 910, the 920 offers voice recognition and Map Share, but with the latest Navcore SE, the 910 offers these too.

Over the 920, the 930 offers Lane Guidance, QWERTY or ABC-Style keyboard, Improved IQ routes, etc. but, you guessed it, with the latest Navcore SE, the 910 offers these too.

So if I can upgrade Navcore above and beyond the version originally designed for that machine, which Go models are actually BETTER then the 910 (doesn't need to be one of the 9xx range)? All I can see is that I'd lose the 20MB hard disk!

Your thoughts would be appreciated!
