Ok, lets see it this way... When you use ADVANCED TASK KILLER you have a FREE MEMORY that gets decreased when you have a WM ROM installed on the phone, also when you install APK's this memory starts decreasing....! So if we keep the OS and installed apps on SDCARD we will have all this RAM available for the OS, correct?

I think you're mixing up RAM and ROM. Let's stick with Android for this example - anything we install it will take up memory on the SD card. Any app that's RUNNING will take up RAM. RAM is used by everything - it's a placeholder for information between the processor and disk.

So Advanced Task Killer will free up RAM when you kill apps. If you remove the app from your phone, you free up space on the SD card.

Make sense? This is all pretty OT too dude... I'm not sure where you should ask these questions either tho lol.

I know that part, now that we have the OS on the SDCARD and we install software it goes to SDCARD, but what about when we install software on Windows Mobile, where is our "hard drive" for the phone? If RAM gets wiped out when we power-cycle the device, where are these programs getting installed at? I install to "DEVICE" not "SDCARD" so there must be some "memory" that doesn't get wiped out on power-cycle....

Think of the SD card as an external hard drive. In Windows, you install applications to the internal hard drive. Android is running off the external hard drive and cannot access the internal hard drive. All applications are installed to the external hard drive with Android.

Also, if any mods can come along and move this crap into a new thread, that would be great.

WinMo has nothing to do with this topic, so I'm done responding to these OT posts... Sorry for dragging it out so long mods! If a mod could break this out into another thread that's not in Android Dev, I'd be happy to continue talking to you about it.

Yeah, I think the easiest way to explain this for him is to compare it to a computer. The internal NAND is like a hard drive, the microSD is like an external drive, and the RAM is like System Memory. Currently, Android is running off the microSD card and does not access the NAND.

Your RAM is not a storage component and does not decrease based on the amount of things you have installed. When you launch an application, it loads itself into RAM as needed. If you launch of ton of applications, they will all stay loaded in RAM, but Android unloads parts of the applications from memory as needed. Do not use a Task Killer in Android 2.2 as you are preventing Android from doing its job in managing your RAM.
