<< With Android (sandbox virtual machine) and Symbian (privilege and certification system), or even a decently configured Windows system (firewalls and virus checkers with daily updates) this barrier is enormously higher than for the Nit. In fact, Nokia don't seem to have thought about security at all with the Nit - and it should have been the starting point and key feature for a consumer device designed for accessing the Internet. >>

I didn't really think that Windows software firewalls were as good as you think or securing Windows wouldn't be the industry that it is. I've seen to many trojans disable the best Windows security, because it was just to easy for the user to accidently subvert system security. Maybe it's obscurity, but I have never really heard of this happening on a linux system - outside academic forum postings.

I would imagine that just being a NIT raises the bar of irritation, as mentioned in another post, for a hacker. Where is the benefit to trying to create a NIT trojan? There is an endless sea of Windows boxes and tools that anyone can use to make quick money. Hacking a NIT via a trojan takes some skill and the pay off just doesn't seem obvious to me - how about you?
