That is precisely the point of a device like the N900 and that's why we love it. The ability to do things that are not popular.
It's not popular to want to drop cellular functionality altogether when wifi is available but it prolongs my battery life significantly and my usage pattern fits perfectly to it.
I have seen all kinds of weird "features" people have implemented on this board that for 99% is a "who would want that" feature.
And by the way torrents are something I use 5 or 6 times a year on the N900. All those little things that you know you can do on the N900 are the reason I never carry a laptop with me unless I'm pretty sure I'll have to sit on a desk and work for a couple of hours. Everything else I may need to do can be done on the NIT. Having it in my pocket along with two japods makes me feel it's alright to leave the laptop at home.
