use. I'm from the UK, living in Canada and I find the UK numbering better, esp since I can distinguish between a mobile phone and a land line.

I understand that calling a landline is the same thing as call a cell in North America, but it's why there is this mess of incoming minutes vs outgoing minutes allowances and "roaming" charges for leaving a state. Annoying as hell and means you can't get a cheap PAYG sim :(
