Since the introduction of nanotube technology in 2025, the level of realism and interactivity available in a Companion has increased rapidly year-to-year.  And as nanotube tech has become increasingly affordable, features once reserved for platinum level Companions have become standard equipment on all but entry level models. 

   The advent of sub-ion inductive recharge cells in 2023 has allowed for longer run-times and a greater array of features than was previously imagined.  Subsequent advances have further reduced cell size.  All current-model Companions will self-charge at 50%.  Treat your Companion to an Induction Lounge Chair.

   We present here a compendium of features that have won customer acceptance.  Many of these features have become standard.  Some are still optional.  Inquire about bundled pricing for acquiring these upgrades.
