I've been using navigation software on my phone for a while now, and I've never resented paying for companies to develop software that I enjoy the use of..

The premium of €50 ($60) is cheap compared to TomTom symbian software which was closer to €100..

My only real issues are:

there isn't a trial version (especialy since its only a beta!),

If this company specialises in developing navigational software.. will they even exist in 6 months time (tomtom had half its share price knocked off straight away when Nokia announced free navigational software) to support the product (develop the beta).

I will go for the Navit option for the time being and hopefuly will get Ovi maps with audio turn by turn instructions soon (which doesnt seem like it needs to be developed to much to give audio instructions..?), and hopefuly favourites aswell..

having said all that - it does seem to be 1 of the most highly anticipated developments of the nokia N900 by the seemingly nokia loyalist community here.. would be in their interests to be nice to you guys and hurry up..
