The iPhone and Touch both have some serious advantages as well, nothing insurmountable, but they are there. I find the browsing experience on those units surprisingly good for such a small screen. I've been tweaking with the prefs.js in my own n810 and have improved the browsing speed a bit, but there are still a few issues.

The main reason that I struggles with the Touch / NIT decision for a while is that it has a full PIM suite that integrates with my Mac. In the end I decided that the ability to tether was far better than any out of the box tools.
