There is one advantage of Philips/Pozidriv I can think of: I have two Philips screwdrivers on my Swiss pocket knife, and they are compatible with a wide size-range of Philips/Pozidriv screws. While for Torx I need to have a set of around 6-8 Torx bits to cover a similar range. My pocket knife is more likely to be with me than my Torx screwdriver set. Interestingly my pocket knife's screwdrivers feel so much better than dedicated Philips screwdrivers. Maybe because the bits are designed to cover the size range, while dedicated screwdrivers are for a very specific size, and they very much suck if you have a mismatch.

Yeah, and I don't like Pozidriv, because it is looks like it is compatible with Philips, but it performs poorly with it, and doesn't have the same margins of tolerance if you have the wrong size of the bit. Philips is _enough_. In fact, for most purposes, a slot screw was enough. I am not carrying my bits collection everywhere.

    For manufacturers on assembly line, if something is not user serviceable, yes, it is OK to use anything, from Torx to Pentalobe to something even more exotic. But if I ever need to service something, I want it to be accessible; I want somebody at least think about it for once. My favorite screw drive type is hybrid Slotted/Philips screw. If it is large enough to be unscrewed by a coin and somebody have thought about it too -- even better.
