I'm seriously considering dumping my landline connection altogether and going strictly with cell.

Can you think of any reason (within reason) why that would not be a prudent act?

I'd worry about losing cellular service first during a weather event when the cell towers go down. My phone service is mostly underground and as long as I have an old fashioned phone in the mix, I still get service even when the local power is out (but the cordless phones go down). Consider the hit cellular took during the WTC disaster and the last few hurricanes. Maybe a nor'easter would have the same effect up there. Also consider how cellular 911 is different from regular 911. Take your phone off hook and dial 911 (or the one-touch button) - even without talking, you will get a police response to your house. Good when you can't talk during a break-in or a medical emergency.

Using a cell phone for your phone number for some financial activities (such as opening a bank account or credit card application) can get you flagged as a potential fraudulent account. Might get you reported to Homeland Security as well. Found that out from my latest banker when I opened an account last year.

Unless you get perfect reception, there's nothing more annoying that being on hold, waiting for 10 minutes and having your phone drop the call. Also, at least in Massachusetts, all of the 911 calls from cellphones are answered by the state police and then have to be transferred to the local police costing valuable time. I'm don't know what the situation is where you are located.
