I use the voice dialing in the car only, but I consider it essential. I might sell my N900 because of this missing feature, and some other basics such as caller name announcement that I really liked. Actually, a lot of th software is a little disappointing. I kind of wish another high-end phone with S60 would also offer 1700mhz - I'd take an N97 instead. A good trick for Voice dialing non-english names on the S60 phones, btw, is to pronounce the name how the voice-announcement pronounces it, even if it's wrong. The reading and listening algorithms seem to be the same.
