Having put it to the test today on a 4h15 flight from SDL to PAJN it worked really well. The approach charts are currently not Geo-Referenced... There is no XM... an you have to manually enter Departures and Arrivals, but it does accept Jet/Victor routing.
It scales down nicely. I prefer to use it in a North Up view until we got into the terminal area then I changed it to Track Up.
Remember that it is a new program and like all new programs, and anything that Jeppesen does, it will have teething issues.
I know that many are using the Foreflight program... The problem is that 60% of what we do is International. Not to mention the fact that we have not looked at NOS charts since our initial instrument rating... Call me lazy if you wish, but why change something that you know works well and more importantly is safe.
XM Weather will be nice, but I am not sure that there will be an easy solution for the 900EX (Dassault can be a difficult company to work with) so in the mean time... We now have a 3rd layer of excellent situational awareness, almost to the point of overload.
Just my opinion...
