You are kidding, aren't you? A status symbol? My father, grandfather, fiance, best friend and roommate are all very important people (all except the roommates are VPs and Execs). They each have one phone number - their cell phone. Reach them there or not at all.
2. Phone numbers are a status symbol. I have two cell phone numbers (personal and work), a work desk number, a home phone number and a pager number. A guy with five working phone numbers looks mighty important.
As for battery life, come on. Charge it over night and keep a spare.
People that pay for home phones and cell phones are just suckers in my opinion.
