Last year I finally bit the bullet and rooted my galaxy note. I've had two phones for what seems like forever, I don't really mind, but the note was getting really sluggish.
So I rooted and flashed aokp on it. I didn't see that much of a difference at the time, even though it was nice to get Jelly Bean on it.
Fast forward to now and they released KitKat for the Note. Now I see a *huge* difference in the phone's performance. It's not like a new phone, but it is a lot snappier. What a shame that AT&T and Samsung have abandoned a phone that isn't even 2 years old.
I'd resisted rooting it because I view the phone as a tool and need it to work 100% of the time. Its why I have never bothered jailbreaking the iPhone or iPad, but the Note had gotten so bad I didn't really have a choice. I even considered paying for an early upgrade.
The tough call is whether I want to upgrade. AT&T doesn't sell phones with unlocked bootloaders so I can't flash a new phone, and don't want to have another phone go obsolete in 15 months, so I'll probably have to get the Nexus. I've gotten pretty used to having a mostly vanilla android phone and going back to touch-wiz, or whatever samsung or HTC sticks on their phones, and being forced to keep it that way for 2 years is a deal breaker.
