Shame they don't come with some of the options
I had some email exchanges with them when they first went on sale. Basically none of the hardware options are available but they sell the software options (quite expensive though - I can't remember the exact costs).
Also the 8GHz TGs went very quickly on the lower priced models so only the 3GHz one remains.
I was hoping some of the early adopters would provide some feedback, but apart from some initial impressions they've been too busy to do so (which is fair enough).
