I absolutely agree about it being silly to have to buy special gloves to use a device. I just refuse to do it.
I don't have the extreme problem you do reading outdoors with accidental page turns. Insects once in awhile do it, but I usually sit out in the sun and not under trees, I guess that could make a huge difference. And it's quite often windy, so that helps to keep the bugs off my reader.
My 2 silver 350s have multiplied nicely in recent months to now include 2 blue 350s! I might sell a few of the silver ones, but the used ones were really cheap I might just keep them for spare parts. All have perfect screens except one that came with my first blue 350, so I swapped it out with a good screen from one of the used silvers.
