Wow, I'm totally amazed I'm actually talking into a microphone reading this review rather than typing.
Installation was not as easy as I had hoped it took me a while to setup the microphone volume once that was done everything was easy to install.
I use Windows Vista business edition and Dragon is fully compatible.
It is not 100% accurate if you speak reasonably slowly it is about 90% accurate, you can always override with the keyboard if you wish.
It appears to be compatible with just about everything, it works with my windows mail, Microsoft works, and what did amaze me it also worked with eBay respond to question and Turbo Lister.
I was asked to transcribe some work for a charity which was over 5000 words, I used this, it saved loads of time, I suffer a little from RSI so no pain either.
A bit of a grumble the headset is not the most comfortable but could always be replaced with a more suitable headset if it was to be used for a prolonged length of time.
Do I recommend, absolutely! It works a treat, is fun to use and also a great tool.
