LOL!
I have like 7 styluses. I'm still using the one that came with my zaurus(plastic 100%). When I use to use my sl-5500, i destroyed around 4 styleses. I still have the metallic ones but I opt to keep those intact. I currently use the plastic og one with my c-3200.
Now for the screenprotectors, I use to use the belkin ones that had glue on it. Worst thing ever made. I got some free ones from streamlinecpu when he gaved them away. It is simply the best one and virtually invisible. I will tell you that these are hard to put on.
My first expirience was so funny. after getting a new screen protector, the screen protector I put on wouldnt stick. So I threw it away and ordered another one while my homemade screenprotector was being used. The second one was placed and for 4 months, it wouldnt stick. I was so pissed off! I started posting how bad they were and man was I wrong. when the screen protector fall, I noticed that I forgot to pull the second layer off(it has two of them). The layer i pulled off was the sticky one and man, i was so lucky when I applied it because it had no dust or bubbles. that c-1000 with that cover was sold to one of the guys here..legodude. anyway, i was given a free one from streamlinecpu when they were giving them away. I am still using it on my new c-3200. no dust or nothing. I became an expert.
anyway, what I did was I cleaned the screen so good in a very moist environment...something like a sawna room. then i removed the layer on the screen and placed it on the z. no bubbles..well yeah it had some bubbles but i pushed them out easily with a squeegy. still using it and no problems.
another thing you can try is use tiny tiny drops of water spread accross the screencovering all surface areas. one bubble of water is enough to cover the whole screen when squished but i used alot of them(be carefull cuz this is for idiots like me) when i placed the scren over it, I just pressed from center out while soaking the excess fluids. worked!!! This method is dangerous and I don't recommend it at all. Im just telling you what I did one time on one of my z's
