I can say, that with the large load of free time today, I have brought my Reshiram to lvl 90, and it is also my first lvl 90 obtained without cheating.
I have also gotten myself a Meinshao, easily leveling it to 65. Gotta love that insane attack and speed.
But nothing too special other than that for me.
I have to say, I'm quite amazed at how little time it takes to level up your pokemon in this game-especially with the abundance of trainers.
