Well its finally arrived and man is this thing fast. My old computer was a 667mhz DVI G4 Tibook and it crawls in comparison. As an example I bought a new ipod nano two weeks ago and converting an episode of heroes to ipod format with visualhub used take anywhere from 60min to 90min. Last night i ran off an episode of heroes in 5min!!! This thing screams. Just for anyone considering getting a 17", so far i don't find it any more cumbersome to carry round than my 15 incher.
