I still use my G4, but personally I wish Apple would start a green initiative where they would sell you an Intel upgrade kit for G3-G5 Macs including chipset/cpu/gpu. If they included authorized store based upgrades, DIY packages and recycling service for discarded parts they could probably make a profit off of this and keep a lot of landfills less filled. I'm very close to trying to start a free forum to try pull people together and discuss this and plans to try to get it done. I'd love to try to maybe do something like making T-Shirts to specifically be worn at Apple trade events by various audience members to get attention. Something is better than nothing. Anyway let me know what you guys think.
