Although there are no presets with the DX10 there are plenty on the net and many of them are great. Since they are in essance 3rd party you can appreciate how powerful DX10 is. I use it for frequent FM-ish kind of timbres. A full DX7 this is not but the timbres it produces are useful. The Fruity version looks intereseting, a interface will help DX10 considerably.
Pros: interesting sounds, simple to use, free Cons: no manual, no presets (but readily available)
If you are looking for bells and sharp digital sounds look no further. If nothing else you will get an idea of how a subset of FM synthesis works.Read Review
