I have both. I need a landline for my broadband and I wouldn't be happy relying totally on my cell phone anyway. I'm not 100% convinced there's not radiation danger from using cell phones so prefer not to use it too much, but I sometimes can't get a signal on it when I'm at home anyway and I dont' fancy having to go outside everytime I want to use the phone.
I wouldn't be without a cell phone though. If only to have on me in case I break down when driving - which is the original reason I got one. There are times when it's been a godsend. When my mum was taken ill the christmas before last (on the day I was travelling to her house for xmas) and was taken to hospital it would have been a nightmare communicating with both my sisters (one of whom was on holiday) over the following few days if we'd not all had cell phones.
