In addition to the ones Serene posted, I'll add these:

Loquats
Sapote
Sea Grapes
Feijoa
Jackfruit

If you consider mango to be an exotic fruit, then it definitely belongs on
the list also.

I have to say that I personally find Surinam cherries, guavas, and jujubes
uninteresting. Rose apples taste pretty good, but I wouldn't pay much money
for them. In the category of "pretty to look at but virtually useless to
eat," I'll add kiwano.
