I thought this deserved it's own thread.
I'm going on just Day 1 with this camera and already I recommend you throw away your 4000 or 5000 or Microsoft VX6000 and get this tiny little camera that makes great FOCUSED pictures.
Careful... Logitech has the Notebooks Pro and the Pro Notebook camreas (they aren't the same).
Also there is the Notebooks Pro Silver and Black... I bought the older Silver model.
Pros of the Notebooks Pro versus 4000:
1) Better resolution and quality
2) Auto focus
3) Lens is covered with a flat piece glass or plastic for very easy cleaning (unlike 4000 which needs patience and a Q-tip)
4) Smaller
5) Colors seem more vibrant
6) Cost less (only while they last from Surplus computers, otherwise much more!)
Cons:
1) Clippy for mounting is probably great for notebooks but sucks for stationary webcam. I used a clear glass to mount it on for now.
2) USB cord is only 3' long. So I had to buy another USB extension cord which ended up (because I was in a hurry) costing more than the camera!
3) Boy that dirt on the window really shows now!
4) Added: low light not as good as the 4000
I'm still messing with the color and light balance but this camera really looks like a winner.
