I have my IFR rating for few years now, and the flying part is not a
problem. I can manage hold on Nav/Com & timer just fine. I am still a
bit new with approach able GPS (my Trimble Approach 2000 is IFR
approach able).

The reason of my post was because I just realized the value of having a
portable moving map. I know their limitation and I have no intention
to use any portable device for approach guildance. However, with a
moving map, I could point the cleared waypoint to the top of the map
while I program my IFR-approach able GPS to do what I need it to do,
and that is the use I am looking for.
