Hi, As the name suggests, I am a BIG fan of the iMac G3. I remembered when they first came out when I was starting school. Always fascinated by all the 'pretty colors' and all the cool things you could do on it. Well now that there are systems far surpassing that of the iMac G3, I'm very much satisfied with what I've got. Throughout my 17 years, I've had an eMac(my very first Mac), a PowerMac G4(with ADC monitor), a 6100, an iBook G3(Aqua/Blueberry), and a Macbook(black). I have been without a Mac for a good 3 years now, and I miss it. I love my Microsoft Windows based PCs, but I want to get another Mac. This time, I would love for it to be an iMac G3. I have a basic understanding in the whole performance and technicality of the machine, but I'd love to hear from others. I want to be able to optimize the machine, and be able to install the latest possible installation of OS X. I would assume Tiger would be the latest that would run comparatively well, but if I wanted to could I go further with, say, Leopard? I've seen around the web that FastMac does logicboard upgrades from G3 to G4? Can this increase performance and speed? And another question I have is... what is the maximum amount of memory the iMac is able to hold? I think it may just be 1GB? But if I'm able to upgrade to G4, does that allow for an increase over 1GB? And also, I'd like to know about WiFi and Airport. Mostly people that have it, and if it's worth it(or should I just use an ethernet cable), as well as the ease of installation. I'm getting it mainly for nostalgia, internet, and basic stuff. So if I got a machine with some form of OS X on it, it would be mostly used for iTunes, iWork(or Office Mac), iPhoto, Safari, etc.
