1. Doesn't every phone these days have a voice trigger to call someone? My old Nokia has and it works pretty well.
2. It seems to require some touching to use. Tap to run app. Tap to start recording. Tap after a status update. Tap tap tap... I thought this was voice-controlled?
3. Searching the internet using your voice doesn't seem that practical. At least by looking at how I use search - using wildcards and such. So it may be a bit restrictive.
4. The voice layer on top of Google and Yahoo will, of course, require a hotspot. Not always available and it may be expensive.
5. I may see this being useful for disabled people.
6. How accurate is voice recognition and pickup really?
7. Is there no chance that Google Voice can become a competitor in the future? They have all the voice recognition expertise - just look at voicemail to text feature. Potential competition from Google must be considered.
8. It doesn't appear to be especially speedy.
In conclusion, it is not that appealing to me but seeing as it is free to try basic features, I may try it out anyway.
