Good computer for the price
I've had the 12" iBook G4 for about a week now. I like it for the most part, but there are some things I don't like.
The speed is great. It's MUCH faster than the previous iBook G3 900 Mhz. My iBook scores about an 80 on XBench, which is a good, usable score. I run Photoshop CS and QuarkXPress 6.0 just fine. If I upgraded the RAM and got a faster hard drive it would work even better. I also really like the new slot-loading combo drive. It's a lot more elegant than the tray that used to shoot out, and it's fast. The keyboard is also a decent improvement over the iBook G3, although still nowhere near as nice and solid as the 12" PowerBook.
Okay, now the bad. The iBook scratches easily, even if you are extremely careful. In fact, it will come out of the box scratched, it's just the type of plastic used. You can't really notice it unless you hold it up to light, but it is there. The Aluminum does not scratch at all. In my opinion, the trackpad button is way too large, the same one as the previous generation. Also, the keyboard keys are attached with really flimsy, cheap plastic clips, so I don't recommend taking them off for any reason. I did, and now my delete key sticks up on one side. Again, the keys on the PowerBook are attached much better.
I guess that's it. I like the iBook a lot, and it's a great computer for the price (only $1000 with 256 MB memory and a combo drive with the edu discount!). However, I would personally prefer the PowerBook, and would have gotten it if I could somehow justify the extra $400 for the aluminum case. It will do very nicely until the 12" PowerBook G5 comes out 🙂
