Haunti has a great point...also, never put bills or any other mail containing checks in your mailbox and put the little flag up. It is literally a "red flag" for the meth-heads who cruise around neighbourhoods stealing bill payments that people put in their mailboxes for pickup. What they do to the checks is called "check washing".
Anyway, in answer to your question, you will love the convenience of online bill-pay through your bank. I love it and the only two checks I write a month are for my water bill (municipal) and my utilities (due to the fact that the entities receiving my payments are in the technological dark ages). The only reason I do that is because the town I live in is very small and I feel better taking my payment by personally and getting a receipt. Writing the check is kind of a hassle, but I figure it's a trade-off for added peace of mind.
