I just got a bunch of things from Seidio.
The Innocase was very difficult to install, could get 3 corners to snap together but the 4th was very difficult. Didn't matter which of the 3 I started with, the last one was tough.
I also got the screen guards. One interesting note, they are labeled Treo 800w but they are really for the Centro. I assumed the 800w and Centro has the same screen but it's not true. The 800w's screen is about 1/8" taller than the Centro's, so I have a 1/8" gap at the top of my screen.
Also bought a new stylus, retractable usb/sync cable and car charger cable. I think I'm set for awhile.
