ok,i use invisishield for the exterior phone shell, its great for thar, but not so good for the screen according to my uncle who had it on his. was sticky on the stylus, and extremely difficult to take off (his comments were that he thought the whole screen would come off first. for the rest of the device though, its great, just take your time putting it on because its so hard to reposition. i have noticed too that it discolours after some time (though only an issue on lighter shells such as that with Bell, mine is white, but now has a slightly blue tinge) and that the edges of the shield tend to accumlate dirt which can be easy to see, but hard to clean.
as for screens, my uncle uses Boxwaves crystal clear, and his looks fine after constant use. i went with boxwave too, but bought their anti glare, went on easily, looks good and is quite clear, though not like the crystal clear one. I use mine outside a lot though and appreciate the muted reflection.

cheers
