To answer the original poster's question: an iMac G5 should
plenty for what you use it for.
As far as the "what does a high school kid need a computer for, you use it for email and word processing"
...
Has anyone heard of video games? Some of the Mac ports don't run too smoothly on older proc. Macs... altough a G5 should be quite well enough
I was an active part of the video team in high school, which is 8-15 kids who make their own scripts, film, edit and such. If we hadn't worked to get the tech department to buy new Intel iMacs at the end of the year this year, the team would still be using the 800MHz-1.25GHz G4 eMacs. And let me tell you. Those were not too fun, but they worked.
At home I enjoy computers. I just graduated from HS, but during the past four years I have had older tablets, older Macs (highest until this month was 500MHz), and tribal gods, who knows what else. Its a hobby, something fun.
Now, I have the family Mac downstairs that I occasionally use. Its a 1GHz ZIF upgraded G4... originally a B&W. I want to get my stepmom going with video editing, but MAN, is that beast SLOW. In my room I captured the other family computer -- a 2.4GHz "First Gen" P4 (slow FSB... 133MHz, 384k L2 cache)
Either way, I want a new Mac for college, but I want a new one for the summer... indeed a NEWER one would be nice, but I am very very pressed for money and can't really afford anything right now, other than the DS Lite I blew some dough on.
In conclusion, high school students need computers. And we like speed, too. Newest models help our egos, or our sense of accomplishment if we worked for the money, or if someone died and we inherited money, we know our money went to something we will enjoy. (My grandma bought my insurance for a year that way)
