I don't know if anyone noticed (I only noticed because I had to set up an iPad from scratch again), when you set up a gmail account you now have the option to sync Calendar (no longer have to use exchange for that!) and notes!
The notes thing is actually funny. I noticed since I've been using 4.2.1 that my notes folder in gmail wasn't appearing in my email...it was annoying me and I didn't know why it was gone. Well, it turns out, if you have a folder in your gmail called Notes it will sync your notepad to it!! So if you write a note in your iPad notepad (the one that looks like a yellowpad) it will upload to your gmail Notes folder as an email! How cool is that??
At least a good thing came of having to re-setup my gfs iPad!
