You are flat out wrong, my G3 is my home rig. I cruise the 'net just fine with Camino and Firefox. I use Thunderbird for email, have Adobe Photoshop 7, Adobe Illustrator 10, NeoOffice, Fireworks 8 and many other apps that are no longer supported but it does what I want. It is dual boot, OS 9.2.2 and OS 10.4.6. Have 3 internal drives, PCI cards for USB 2.0/1.1, Firewire 400, ATI Radeon 9200 vid card, 1 GB RAM and it runs 24/7/365.
It doesn't do video well, it is slow running iMovie 3.0.3, runs iTunes 6.0.4, Audacity 2.0.2, and many other legacy apps. I'm not a person who needs leading-edge technology. It works and the electric consumption is very little, 9 watts at 1.1GHz.
I still boot into OS 9 to use ClarisWorks 2.1 for my MPG spreadsheets, to play legacy games such as Unreal Tournament GOTY, Links Pro and Links 2000. It all depends on what you do with a computer. I'm not a Facebook member, nor a Twitter member, nor LinkedIn, complete waste of time IMO. I like that I can come home from work and it is running Folding@Home, waiting for me.
It works, period. If I want something faster I turn my sat around and use a 1.25GHz eMac. I'm old school, not a first-adopter, not one to spend money on new, leading-edge hardware. People today are inpatient and spoiled. I come from a background where key punch cards were the norm and line command was the way to use a computer before 1984.
That said, my work unit is a quad-core MacPro. The only difference, it runs the latest software.
It's fantastic to know that there are people with the time, patience and wherewithal to get G3 systems working at such a high level. You sound like you can do most of your upgrades and maintenance with little assistance (this makes you somewhat unique among G3 users), and I don't know that I've ever seen you post here before.
But someone new to Macs who purchases a G3 is likely going to be very disappointed if this is their entry level machine.
You've moved in small increments from the very beginning. I've had several Apple laptops and desktops, beginning with the 520c PowerBook, and I never had a problem with patience or with feeling left behind by new hardware. Those early machines performed much better than their Intel counterparts. It was so much easier to upgrade and maintain my Macs.
My apartment building burned down about three years ago. I lost almost everything, including my 1GHz PowerBook. Soon after, I bought a 1.33GHz iBook from eBay for $200. It was in pristine condition (I think it was from some business office that was either no longer in existence or was upgrading to something else.)
I was homeless for a short time, and my iBook served me very well. (I'm very partial to PowerBooks and iBooks.) Once I got back on my feet, I spent about $70 to upgrade my iBook. Replaced DC-in Board, replacement battery, 1GB of RAM and a new AC-adapter. I don't have an SSD or a SuperDrive, since there are limits to how much I'm willing to spend to keep my baby running.
I certainly don't need the latest-and-greatest hardware, and I'm very patient with my iBook. I simply don't like the Intel Macs. They just don't feel right. Plus, I started, I think, with System 7, so a large part of my computing experience is from a time when manipulating hardware and software was both much more simple than it is today, and certainly more fun.
I think getting your hands on a PowerPC Mac can be a great experience. Mine certainly has been. But it's not for everyone. I imagine that within the next year or so I'll upgrade to a late, second-hand MacBook in order to run Mountain Lion. But I am in no hurry to do this. I like my iBook, and I will continue to use it as my main machine as long as I can.
On a final note, during the recent hurricane, I spent a great deal of time away from home, in local restaurants, coffee shops and the local library. I often got comments and questions about my iBook. This happens frequently when I am away from home. More recently, I had hip replacement surgery followed by inpatient rehab. My iBook got a similar amount of attention. In both instances, most people were fascinated to learn that my iBook is seven years old, that the display was as sharp as it is, and that it handles streaming video so well.
I'm dedicated or loyal to the PowerPC. I just like using much more than anything else that's available.
