I don't suppose I'm adding anything here to what's already been said by more experienced pilots, but...
My view was that if you can afford to obtain the 'latest technology', then why not add it to your inventory?
I will certainly been using trad methods to plan any flights I carry out (until I think I'm invincible, anyway - and that's several hunderd hours down th line
), but I like to have it there as another reference...
I've used trad methods and have still had a couple of moments where I've got sweaty palms as I think I might have strayed - and a couple where I actually have... so a greyscale screen confirming or denying my current position would have been an aid to me.
Now - if only I can find one that wakes me up at my destination... kidding, kidding...
