HOW TO SELL YOUR WIFE (ON A NEW CAMERA)
Want domestic tranquility? Want a happy wife?
She wants great photos of her kids and family.
Don't ask her to buy a camera. She could care less about equipment. Women hate gear.
Tell her you're getting the family what it needs to create priceless memories which, presuming you backup properly, will last forever. She wouldn't want you to let these memories slip away unphotographed. You want digital because the memories can be copied and safeguarded elsewhere in case of fire, and in case of fire you can grab your spare hard drive and take everything with you in one small drive.
