Where are the apps stored on the Android phones? Is it the RAM, ROM or SD Card? I'm sorry for the "dumb" question, but I'm really confused. The reason I ask is I'm going to get an Evo or Nexus 1 (leaving Blackberry) and I'm wondering if the apps take a lot of space or can you have a large quantity of apps? Also, do they take up a lot of memory if you don't shut them down when done using them?
Thanks

No question is dumb
The RAM is just like the RAM on your computer.
The ROM is like the hard drive on your computer. It holds the OS and the applications.
The SD card is intended for storage. Things like music and other media. You can put apps on it as well if you have rooted the phone and made a suitable file system on part of the SD card.
Some apps are big, most are very small. For example I am using 30 different 3rd party apps and they use less than 15 Mb in total.
Apps only take memory that's not used by anything else. The OS is programmed to shut things down as needed. Like anything else, there are tweaks to make it even better.
I second this as I am also leaving BB as soon as the EVO hits. And what about apps2sd? Is that a custom rom or future feature?
It's both.
Right now, you can runs any or all your apps from the sd card if you're rooted.
Google has announced that apps on the SD card will be a feature in a future release.
