It's much more convenient on the left IMO. And no headphone jack? It's not a big deal. If you just don't want this phone, it's fine, no one HAS to buy it. I love it, and many will as well. If you feel like it's not for you, it's your call man.
The note 10 actually comes with a power button. All of the buttons are on the left side. You have the volume rockers and the integrated bixby / power button. By default, holding down the power button brings up bixby. However, this can be changed in the settings.
