Hi y'all I am a big mac junkie; currently have a 13.3 unibody MB (2.4) and 15" MBP (2.8/SSD) and 17" MBP (2.4) and a pair of 15" modded to wuxga and previously had a first gen MBA. But i always missed an early PB 12" G4 i had that died from a burnt out dc power board. Anyhow, saw this great late 1.5Ghz PB G4 12"/superdrive and i pounced on it for $475 (i know a little pricey for these days) but what a beautiful machine that is nicely put together and so compact... The screen is sharp and though it's my slowest machine, it just has a certain je ne sais quoi... I am very happy. Just wondering if it's worth putting 10.5 or leaving 10.4.11, it only has 1.25GB of ram. Thoughts? Oh, it does have the two-finger scroll feature but the touchpad is tiny compared to current-gen mb/mbp also the keyboard feels very nice though it's not lit..
