First off, I just want to say how much support I've already received from this forum community. Not only was the community here instrumental in helping me select me Macbook, but you showed me that I don't need to spend $700 for a 4gb ram upgrade. Ok, so here it goes: I'm not a super techy person. I'm the guy who knows his tech stuff from watching all his friends do it, but here's my chance. I'm coming into possession of a G4 later tonight. My information is extremely limited, but here is the information that I have: 1. Its a G4 2. The case is Green 3. Aside from missing an HDD, its in perfect working condition I've got a ton of spare drives from old computers laying around so I'm pretty sure that end won't be problem. Even if it is, that's what, $50? My question pertains to what OS would be best for my new found g4. My initial research seems to show that this guy could, in theory, take just about anything from tiger to panther to linux or even leopard if I'm super lucky. The sole reason I got this mac is so that my daughter can play video games. She's four and loves to play on my old PC. She's particularly fond of http://www.jacksonpollock.org/ . I downloaded the .swf file and she plays with the drawing for hours. So, what OS do think is my best choice? I was considering either a version of OSX running emulation where needed or just going to linux. But what do you folks think? Your input is invaluable.
