Just recently received my new HTC Desire, an Android 2.1 phone, and very nice it is too. Unfortunately it does not come with the Google voice to text functionality built in, something I really wanted.
After digging around on the net (I recommend androidforums.com if you are new to the Android phone OS) I found the following hack, which requires you to download a couple of files (Google voice search and a modified keyboard) and you are good to go.

You can then use your HTC Desire for hands free dialling plus voice recognition for voice to text e.g. for sending text messages.
