I use MemoryMap Navigator with my PPC/GPS setup, and I think it's fantastic. Yep, it lacks a few features which I'd like on there, but having a moving real-time display using actual CAA 1/2 million or 1/4 million maps more than makes up for that. I'd recommend it to anyone.
I'm currently trying to find a cheap "tablet" style PC with a larger display than an IPAQ (but still small enough to be realistic in a cramped cockpit), so I can use the same software to beter effect - anyone have any recommendations ?
