I bought mine brand new just before Christmas and though I haven't done any long trips yet due to a thumb injury, I'd have to agree with most of your comments. The buffetting is quite sever too and most owners seem to find the bigger screen a better option, from what I've read so far. All in all though, I'm still very happy with the purchase.
And he sees the vision splendid, of the sunlit plains extended,
And at night the wondrous glory of the everlasting stars.
(A. B. Paterson)
