Go Launcher is a great launcher, but it runs pretty "fat"...fat meaning it eats RAM.
This is what I dont understand, you kind of contradict yourself. You say on one hand the Android OS handles RAM differently and a lot more efficient than how a PC handles RAM, but then you state the quoted...
I know there is no doubt that more RAM, the better, hence why the top phones have 2GBs, NOT 1GB. And RAM is RAM, it is in essence just like a PCs RAM, its accessing "randomly" memory, and the Droid HDs are FILLED to the brim with bloatware taking up valuable RAM space, which is also the reason a lot of people root their phones, to rid of this garbage.
I completely agree with the poster, I have noticed my phone lag many times, example, press an icon and it just sits there for a second, lagged out, then I open my sweeper program and I see all this garbage floating in the background.
My biggest beef with the phone is the lag, which is clearly due to the RAM only being 1GB, the processor is plenty fast, but no doubt should have had 2GBs of RAM, and MOTO knows this, they packed this thing up with bloatware to the very limit, from my experience with memory, there should ALWAYS be at least HALF available at all times, and that goes for phones, pcs, tablets, whatever. There is a reason its called RAM.
EDIT: And as much as I HATE saying this... my wife has an iPhone5, which has 1GB of RAM too, and runs smoother. NOT saying my phone doesnt run smooth, but RAZR HD vs. iPhone5 in reference to RAM and its usage, the iPhone is better at it, and I can almost guarantee without looking it up, the reason is there is less bloatware taking up RAM.
EDIT AGAIN: I had to look it up LOL, and this video proves there is a difference:

Now, its true, the OS handles RAM a little different, the way it handles it is if becomes overloaded it CLOSES out apps... 2GBs there is no need to close out the apps, and 4GBs and so on, check the video out.
