Menu Glitch
When composing a message and the corrective text box was open on the screen and you hit the menu/BlackBerry button the wrong menu options would come up (Reply instead of Send).
THIS IS FIXED WITH .75 File Free/Memory
I have about 6MB more file free after the update. We'll see if the memory leaks are as bad with .75 as they were with .65...
EDIT: AFTER REBOOT I HAVE ABOUT 20MB MORE FILE FREE (51MB)
Accelerometer
No lag, screen flips almost instantly (about 1 second)
Fade Effects
Programs and folders fade in and out quickly without lagging
Camera
Loads quickly in about 2-3 seconds but still hangs (black screen) for 2-3 seconds when taking a picture. (Somewhat understandable as it's capturing 3.2MP worth of info...)
MySpace and Facebook
These apps are usable in landscape mode now without the annoying "compatibility" mode.
Responsiveness
After hitting send on the menu after composing a message, the screen jumps back to the message list MUCH quicker than .65.
Multi-Tasking
I frequently browse and message at the same time, I used to experience a lot of lag, this has also been resolved.
Incoming Messages/Incoming and Outgoing Data
With .65 I experienced lag when emails came in and I was composing a message. This no longer happens, incoming messages are invisible.
I use Google Sync for Calendar and Contact OTA synchronization and when the auto-sync started the phone would lag and freeze. So far .75 has seemed to fix this.
Typing
I've become quite accustomed to the touch keyboard and can type rather fast. With .65 it couldn't keep up with me and would miss an entire word, with .75 I can jam out on the keyboard and it keeps up!
Reboot Time
Reboot time is roughly cut in half!
A BIG THANK YOU TO RIM AND VERIZON FOR GETTING AN OS OUT QUICKLY!
