Absolutely its worth the time to get it right.

What kind of app are you building? Maybe you're selling something. You probably want users to get through your check out form as fast as possible before they change their mind or get distracted or frustrated.

Or you're building an app for data entry and people are filling in lots of addresses every day. They would appreciate you saving them time.

Either way, spending a day or two to polish up your form can be worth a lot.

Not saying its trivial to get all the edge cases right, but I'm pretty sure we can do better here.
