Right! I'm on it....
Just downloaded the beta. I've been playing with Centrafuse but am not over-impressed with Destinator (I'm ex tom-tom, and I'm only ex tom-tom because my PDA died!).
I'm on my way to getting a version of Mappoint Europe 2004 (annoyingly, I've got S&T 2006!).
If everything goes to plan, I'll be putting this beta through its paces by doing a 500 Mile Manchester - London - Southampton - Manchester run this weekend.
