    what's the difference of having apps under /system/app as opposed to /data/app, besides /data/app can be removed and /system/app is read-only?

    any thoughts on this?

    thanks.

    /system/app apps do not need to be signed.

    Here's my opinion....

    The phone is basically a small PC, what happens to a PC when the memory gets full......? I like to keep as little as possible in /system. Anything that I can get from the market, like Search and Maps that devs put in /system, I take out and download from market. I don't use LWPs so ALL of that stuff comes out, its useless to me.. battery killers are all they are...

    I do a lot of themeing and now with tools like APK Manager, there is no need to put themed apps in /system because they can be resigned and installed to /data.....

    But this is just my opinion...

    Market updates with /system apps that aren't "supposed" to be in /system is a pain. The market will install an app into the /data/app directory by default, so if you have something like LauncherPro that is a non-system app by Google's definitions, but it's in your /system/app directory because it came pre-packaged with your ROM, then if you update from the market you end up with two copies of it -- a deprecated version in /system and the current version in /data.

    You also lose any theming when you update from the market, but that's nothing new and iirc that's true for any themed app regardless of whether it's in /data or /system
