Intuos 4 Medium. It's really cool! At first sight, I was trying to figure out a personal configuration but it was hard to achieve the perfect combination between the tablet configuration and PS brushes pressure, but finally got it (I don't want to kill the nib's pen so fast!).
Mmmhhh... I see... over a year............. How much pressure do you apply to your pen? I had to set it very sensitive, in order to avoid pressing too much. In fact, I don't apply pressure to it. The nib of mine is getting short, but that was because at the first use I didn't set it up. And what are the other nibs? I have here like a little black russian glass where I put the pen, inside it has many more nibs.
There are 3 white ones with a rough surface, another white which is soft and it has an spring near the end (?). Then there are 6 black ones. One is white in the end, and the other 5 remainings are just black. The one in the pen is black too. What are these things? Another question is if the nib can be pushed out of the pen, like with this: [link] You know, you push a button located at the end of the pen and more graphite becomes available. Hope this is also possible here!
