Coming from .320 your phone will be snappier, the blue glow over the keys is stronger and typing is better (in my opinion)... Also you get the option to show the key indicator while you type (like the iphone, though I like without it, less distracting)... Some people find battery life improved (seems normal to me)...
Also if you hit BB key from home screen and select "Options" from the menu the layout for setting icons and wallpaper is changed (for better).
In .451 I have some bugs when selecting text... basically when I pull any of the start/end markers for selecting, and then release the screen also move like when you sweep which is the wrong expected behavior... no big deal... but hopefully is corrected in newer OS.
If you read other people posts you will see that the Lock function has changed (not in .451 though) where it use to password lock the phone after hitting the upper left key, now it only locks the screen and if you want to password lock it, then you have to click the on-screen icon...
I, also, have noticed a great improvement in the typing. You no longer have to hover above the keys, but can actually click right on the keys. (I still hope they bring out a calibration feature)
My phone definitely feels much faster and doesn't sit and "think" as often. I still occasionally have a fatal exception, but I've been unable to track it down. It might have something to do with a third party app so I'm not blaming the OS yet.

For those reading this instead of the regular threads I did an OTL update today and everything worked well. The update used about 35 % of the battery. I did not time it as I put the phone in a drawer during the update and went to a meeting.
