As far as mesh goes
I bought a nice Boxwave mesh. I already own a rubber one, and it's very nice, so I bought a mesh one going by reviews.
The thing is, if you rub your finger on the tip and it's rough. VERY rough. Now, I don't know what this is. I was under the impression it was some kind of metal. My immediate thought was "Oh no", but then all these people are saying it's safe. Whatever.
But I can't help thinking that even if the tip itself doesn't scratch (microscopically), the uneven tip will catch debris; again, common sense?
As far a the Wacom goes. I hated it at first as I had to press down too much, as the dude above did. But for some reason I like it now. It's as good as the Boxwave, just a bit different. It's heavy, which is both a plus and minus I guess.
YMMV
