Hey, I have a little dilemma here. I have a Powerbook G4 12" that I bought in 2004. I LOVED this thing. This computer was the reason why I believe in the 'Apple' way of things, and want to continue using it. The thing is, it's seen better days. Way better days. This was my main computer during my college years and it's seen me through everything. I'll admit I'm pretty rough, and this thing took it all like a champ. The case is bent at a few places, with dimples and dents all around - and what made me move on was one day it seemed to loose all I/O function. So I kinda just put it away and got a desktop. Now I miss Mac OS X, and I'd like to just reformat it, get a copy of Mac OS X Leopard and use it as my main computer. Here's the thing, I know it needs some reconditioning, but what? The thing is, it boots. It takes way longer than it normally did to boot (the HDD is making a clicking noise, no matter 'cuz I'd like to upgrade the 60 GB HDD to a higher capacity anyway), but now my airport wireless card doesn't work, says "No airport hardware installed" The DVD drive doesn't read discs anymore. It takes in a CD, reads it, spins, then spits it out. I don't think the USB ports are working either, i've plugged in my ipod, and nothing happens. But I think the network/ethernet port is working as I was able to plug it in and connect it to the internet. Now my questions, are (1) what do you guys think is wrong with it? (3) what should I replace first to bring it back to speed? (2) I'd like to upgrade it (I'll start with a new HDD, but what else - more memory - it has 512 MB, superdrive perhaps, is the processor upgradable?) or (3) is this thing even worth upgrading, or should I just cut my losses and move on? I really don't care about the cosmetic issues, I think it shows character, and the fact that the thing still boots to the dock and the display is still as bright as ever shows it may have some life - just need some direction on what to start with it first? Thanks!
