I hate the new small keyboard, way harder to text than GB keyboard. Always find myself hitting the suggested words on top when I have to reach for a top row keyboard. You would assume that a phone with a bigger screen that you would be able to text more accurately, guess not.
Also, the native e-mail client on Android still sucks after the update, you still can't make it so when you delete a message on your phone it doesn't delete it on the server. Lots of customization left out, was hoping they would address this with ICS but I guess not either. They did fix it so I could delete accounts from the e-mail app itself, which is very nice. It eliminates going all the way through the menu to the accounts page, saves about 30 seconds of your time.
