MintPPC is pretty good. It comes with most applications bundled with modern computers, even though it's hard to get Pidgin to work. Your biggest problem might be using internet security. Even though the original AirPort card supported WPA, it was impossible to set up on my clamshell iBook.I know you're looking for an alternative OS, but the iBook G4's can run Tiger quite well. If you have one of the later models (1.33GHz or 1.42GHz), you'll have no problems running Leopard. Some people like MintPPC, which is a Debian Linux flavor for PowerPC Macs, but I don't have any experience with it. To be honest, there's not really any options that are worth using on a G4 because all the G4's are fully capable of running Tiger quite smoothly (so long as you max your RAM and optimize your OS).
What's the specific model/specs of your iBook G4?
What's really ridiculous is the amount of sellers charging people outrageous prices for Leopard disks that have already had their licenses used. This is why I don't get mad when people bring up downloading it instead of getting ripped off. Don't get me wrong, I'm all for supporting Apple (I have retail disks for OS 9, 9.2.2, 10.1, 10.2, 10.5, and I purchased 10.7 after I received my Mac Pro, which had 10.6 installed when I got it), but I'm not going to get mad at someone who refuses to give their business to sellers who willingly rip people off. Apple receives ZERO money from me buying a USED Leopard disk for $150 when Leopard's MSRP was $129.99 upon release. Installing OS X from a used disk is just as illegal as downloading it (unless the OS was deleted from all computers that disk installed onto...which I really doubt every seller actually does).Leopard disks (retail installs that is) can cost you your first born child. It amazes me how expensive it still is compared to SL!
is flash any better than on Leopard? Im seriously considering installing it on my Powerbook g4After my last post I decided to give yellow dog Linux a shot on my powermac g4 digital audio (733mhz G4 - 512mb ram - 32mb nvidia) I was even able to get java re 6 running a play some slooooooow runescape.
I decided to check it out on my 700mhz g4 DA, so far it looks solid, JRE6 preinstalled is nice. So far no sound, but it appears to be a common issue. 8-bit color Is kinda weird, I will need to look into that....smokes Yellow Dog, which is unsupported these days.
