Perhaps there is something about:
* Essentially "dead" -- no more development, no more support from Microsoft
* Stuck in 32-bit (unless someone implements the entire engine in 64-bit) -- though 32-bit software does run today, it's a "2nd-class citizen" in that it requires an emulation layer to operate (i.e. doesn't run "native"). Essentially VFP is in the same status that FPW was in back when 32-bit OS became the norm. Don't be surprised when 128-bit OS comes around and 32-bit support gets dropped.
* These points could be a "dealbreaker" with customers.

If it's an update of an existing software then you could probably get away with sticking with VFP -- for a new product it's probably not such a good idea.

>Ouch. Do you mean people think of VFP as dated or do you mean its abilities are not up to modern snuff?
