Maybe a daft idea, BUT....
We use internet a lot, but mainly some forums, email and research etc.
We use phone a lot.
We are on bundled BT exchange, so when I add up line rental+calls+broadband+a mobile contract = a lot.
What about going 'no landline'? eg Iphone or similar that we can (usually) check emails/forum surf etc, and that can be used as a modem if we want to use the desktop (eg upload flickr pics). I can get some silly cheap deals on minutes/texts and loads of data...
Daft? Downsides? Anyone else do it?
