Vista *only* uses 450MB of RAM? Here's a look at my XP Task Manager (System processes in red):

107480KB, or 104.9MB of memory from the big programs (probably another 10mb or something from the rest)
Vista's Aero looks nice, but it lags when you drag windows, which is pretty sad.
Vista's security settings are a scale from Very Annoying to Insecure. I think Service Pack 1 came out rather quickly, but that's what happens when you release half an operating system on top of another one.
