ok first of all, to the OP, you do not have long finger nails be any stretch of the term. I would say for long nails, mine are just about in the middle, and they are way longer than yours, way shorter than those girls with the dragon nails all blinged up.
i have very little problem using my iphone despite the longer nails, but i do use it differently than other folks. i notice for instance that i use my index and middle finger (instead of thumb) flat on the surface to pinch and pull it happened very effortless that way and just stuck
and the glove thing? i got mine to work thru fine leather gloves, not great but enough to unlock it and make a call
My Garmin Nuvi has a great touch screen.
It cost me just as much as the iPhone would... (if I had one
)
it is soo funny and frustrating at times because i have a Nuvi on my jeep as well and going back and forth from a conductive touch screen (iPhone) and a pressure touch (Garmon Nuvi) means that i have to constantly resent my behavior
