Ping pong / table tennis (depending on how seriously you take it) can be a VERY good way to get your steps in. In a 2 hour session I get about 8-10 thousand steps. This is 4 to 5 miles. It is low impact and you can really get a good sweat on.

There should be a Bluetooth headpiece (over ear preferably) that has normal functions, but ALSO will replicate the “Note to self” feature, where you tap the main button, and say “note to self” then say what you want the note to be, and have it sent to your email. That alone would be a “killer product” for me. I miss this so much.
