Fruits and Nuts: Does it make sense to plant a 2-in-1 apple tree?, 1 by pennefeather

I decided to add a fruit tree to my yard this year. After doing some research, I found that I would need at least two apple or pear trees for pollination. I would really prefer to plant just one tree though.

Now I'm considering trees that are grafted with two different types of apples or other fruit. Do these trees really grow well or are they more of a "gimmick"? I hate to spend the time and money on something that isn't going to work in the end.

I am including a link to an apple tree that Stark Brothers has. This is their photo.
