I've got one, too. I like them mostly. Any time I dont know where a family member is, I can just call their cell. If I'm going somewhere, and someone needs something (milk, flour, ext) they can just call my cell and tell me instead of waiting untill I get back and sending me out again. Plus I like having a clock, notepad, camera, internet, game with me all the time, in one little package.
I dont believe all that stuff about cell phones giving you brain tumors. They said the same things about color televisions and microwave ovens for years. "Scientific studys prove!!" and all that bull. I've been couped up in front of one or the other for all my 21 years and prior, and can attest to being brain tumor/birth defect/cancer free. Americans have a long standing love affair with media induced hysteria.
I actually hate landlines, I keep nagging mom to drop our landline in favor of the cells, since noone EVER calls it, exept for 15+ telemarketers a day. Annoying as hell.
