We can keep apps in \system\app and also in \data\app.

What are the benefits and costs, or pro and con's of placing the app in one directory vs the other. I know that it is slight more permanent in \system\app, but does it go faster, take more or less space, other difference?
 
system has its own partition. if you put apps in there (not all will work) then it wont be in /data space (more space for market apps) hwoever as soon as there is an update it will be downloaded to /data/app and then you will have double the space taken :)

this is why i use something like titanium backup and one of its schedules is integrate updates into system. it takes stuff like google maps and makes sure the latest version is in your rom not taking up your space for apps :)

Thanks, I didn't know that titanium backup could do that, and I was confused if the updates were using "double" space.

I don't know what the deal was in the first place, but Kid showed us how we can move the ICS Camera app from (I think) /data to /system and it works perfect. I don't know if this was necessary to make it more compatible or what but it works, and well :)
Do believe it was taking the stock camera.apk's place, but thats a common trick ;)

Basically, system/app is for system apps, data/app is for user apps. Apps in data/app can be uninstalled w/o root, and the rest has already been explained. lol
