I think there's something to the fact that the iPhone's auto-correction is more suited to a touchscreen than the Blackberry's. I've found that while the Blackberry's spell-check is very good for people who sometimes make spelling errors, the iPhone's is much better about fixing fat-finger syndrome.

I would almost be tempted to say that the iPhone's spell-check puts more weight on where keys are located, while the Blackberry's is more of a straight dictionary search

My Storm seems to have a feature that automatically resets the phone at random intervals. It handily solves that problem, but can be annoying when you're actually trying to do something with it.

Seriously, though, the sluggishness of the phone is a big drawback. If it could keep up with how fast I type and not randomly reset I would be very happy with it.

I'm a philosophy major, so my view may be a bit biased. I've found that it's much easier to answer the practical questions accurately if you've got a good grasp of the theoretical questions.

So, to use your example, asking whether or not all viewpoints are valid is asking more fundamentally whether or not all viewpoints are true. If truth is defined as being in conformity with reality, then it would really help to have at some point asked what reality is.

In my mind, Metaphysics is the fundamental question of philosophy, with Anthropology running a close second. Everything else flows naturally from a proper understanding of those two fields.
