Hi, I'm interested in picking up a 15.2" powerbook. However since browsing these boards and reading elsewhere, i've come across a significant amount of complaints regarding the new AlBooks. I'm pretty neurotic when it comes to nitpicky things like the latch not closing properly and what not, so I'm a little turned off to that machine. It seems that the previous generation had far fewer complaints In any case, I'm more concerned with the performance and usability improvements over the last batch of TiBooks, how significant are they? Are the new Albooks much faster then the TiBooks (1.25 Ghz vs. 1 Ghz, considering G4 7455 vs 7447)? How does the battery life compare between the two? Yeah, I guess the backlight keyboard and airport extreme are nice, but if the changes aren't really that big, I might just try picking up a lightly used TiBook for less, anyone have an idea the price range they'd fall under. Thanks.
