I know I'm late on this, but I have one item that may make the couple's life easier: the Shake-N-Wake.http://www.amazon.com/Silent-Vibrating- ... B0027A573Q
It's an alarm that vibrates to wake the wearer up and doesn't disturb the other person in the bed. (It's also great for people who are hearing impaired.) My then-boyfriend (now fiance) bought this for me because I have to wake up much earlier than he does, and he was being disturbed by the alarm on my cell phone going off. He generally has a pretty hard time getting back to sleep after he wakes up for the first time, and although he sometimes still wakes up when I get up, since it's not a loud, startling noise, he can get back to sleep easily. I've been using it for over a year and it's been great. The picture on the site shows a person wearing it on her wrist, but I put mine on my ankle.
So, husband in this case: get a Shake-n-Wake. You can wake up as crazy early as you like without disturbing your wife, and then she can use the audio alarm to wake up at an appropriate hour. No fighting over a time that works for both people. Everybody wins!
