well for s60 with europen map its 80 euro i'm willing to bet its about the same on N900 if not a little more b/c the low amount of units to sell to.
i purchased a 5800 new 13 months ago for 200 euro
so now i should easily get a second hand one the same price as sygic.
Its going to be a big rip off as they have no competition on maemo 5 they have no reason to make the price competitive with anyone else
