Are we sure it's a bad thing when RAM usage goes up?

[Aleki]

I have yet to have my TP2 lock up in 6.5. I do reset it out of old habits, but most of the time its because of uninstalling or installing apps that require resets. I notice with 85% usage, the phone is actually snappier than it is originally at bootup

edit: one of the guys from the apple store wanted to see my phone (probably trying to spot an error so he can knock WM). ram usage was at 88% and the phone was moving along very smoothly with everything ready to go. after a few minutes of casual talk, and him playing with it, he handed it back to me with a mildly frustrated expression on his face
