SX210IS vs. SX20 IS

[ReCKLeSs_X]

Hey all, I'm looking to get into photography and have narrowed my choices down to these two cameras. From my basic understanding they are powered by the very same technology but are in two different forms. I understand that one has 20x zoom with the other only 14x, but other than the physical size, is there any other noticeable differences that will help me make up my mind?
I'm looking to basically delve right into the manual settings and fool around with things like shutter speed and ISO for controlled motion in my photos.

Now this question would have been silly a few years back when the two types of cameras were more well-defined, but I feel like the lines have blurred very much.

I am looking to get the best quality pictures. I actually had my mind set on the SX20 IS for a while but then I started reading about the SX210IS. Obviously if I am not losing much functionality I would much prefer the compactness.

Thanks for your time!
