Since none of the radios have yet appeared "in the wild" for us to play with, I guess all we have to go on is the manuals....but from what I have head, they are still doing software updates, so who knows for sure how they'll work? I bought one on speculation that I'll like it - for me, the dual monitoring is the big feature that I wanted. Granted, it's my second Comm, which means that now I can listen to three channels - but I am used to having multiple communication loops in my ear at one time, and like having as much info as I can. If I have one, I want two, if I have two, I want three....
I really liked the multiple channel feature on Louise's SL-30, and the icing on the cake for the A210 is the huge number of memory slots organized into groups. Yeah, it'll take a little while to program, but it will be quite nice - and I might even get it hooked up to auto-channel from the EFIS someday!
For plane old VFR on a budget in simple airspace? Probably overkill, but as Captain John said - for the group buy price, it's a darn good deal!
