First I wanted to thank you for developing what is hands-down the best keyboard available for Android. Even after trying Swype I keep coming back to SmartKeyboardPro.
The only suggestion I have for making your product even better would be adding a setting that allows the user to change the Voice Input button to activate Vlingo instead of the built-in Google voice recognition. Vlingo provides their own keyboard (which is just a duplicate of the Android keyboard) with their own microphone button, but switching between the Vlingo keyboard and SmartKeyboardPro is a pain.
After some testing I've found that Vlingo is often much more accurate than Google voice recognition and I use it heavily for everything from posting Facebook updates to taking notes on books I'm reading.
Thanks for at least considering the idea.
Code on!!!
