A persocom is a computer of the 22nd century future that can do all the things you want it to. It can go on the Internet, make phone calls, and receive e-mail. It can take many forms, the most noticeable being humanoid persocoms who are distinguished from humans by their bell shaped ears.
Because its an electronic being, it charges by either solar power (taking it out for walks) or by pressing the ear where there is a charging cord. The cord is then plugged into a wall socket adapter.
