The new application comes in a zip file, you un-zip it on the root of the Internal Nokia N900
Now, let's get to the business of running the application. Firs, it has a wide range of maps (all of Europe, at the price of ~60€). Then, it has many voices available. I would have liked a female voice for English, but the britt there is quite entertaining.
Then, the routing. It starts fast, it remembers the last destination (although, the settings get lost if you don't exit the application the right way... bad programming) and it is easy to use. Also, I like that I can change the things that I want to see (it has quite a nice personalization ideas). The a-gps might come handy, but here, in Finland, I don't make use of it. Another thing was that it had some routing that was not quite the best way to go around, but again, that is hard to please everyone. After all, it gets you from point A to B in the best way a computer can get you.
So, conclusion? I love even more the N900. It has everything that a Linux freak can want (well the most anyway). I hope that Nokia will keep this thing up and with Intel we will see better devices, with better UI and having the best of Free Software running so that more developers will join the fun. Yes, it is a lot of fun to have the N900
