Speed
The G3 is a three or four year old processor, but it is still sitting in Apple's consumer lines, even though the general consensus is that the current G3's run OS X too slow for it to be worth using. (I have heard this from three different guys who are total Mac fans--one owns a 400 MHz iMac G3 with 512 MB, another owns a 600 MHz ibook, the last a 500 MHz iBook. If they are wrong, by all means, correct me.)
In the time the G4 went from 3-400 MHz to 867 MHz, the Pentium went from a 1.2 PIII to a 2.0 GHz P4.
Are RISC processors going to wipe the floor with CISC processors at the same clock speed? Absolutely--but here's the problem--WE (APPLE) ARENT RUNNING AT THE SAME CLOCK SPEED__WE ARE RUNNING AT LESS THAN HALF THE PC COMPETITOR'S CLOCK SPEED.
What's that you say? Bus Speed and RAM and Video card make up total system performance? Well, Apple is behind there, too. Apple tops out at 133 MHz bus speed, but the bus speed for Athlon is 266, and 400 for P4. Macs ship with less RAM (and lower speed RAM) than many PC's (used to be 64 MB, just in the last year, up to 128MB). Finally, Consumer Apples for 1500 bucks ship with a 8 or 16 MB Rage ATI card, a 5 or 6 year old graphics card (around 1994 or '95). A $1000 PC ships with a GeForce 2 32 MB card at the low end (which wipes the floor with a Rage card, and, incidentally is the same card that ships with the high end Power Macs).
I am as big and ardent an Apple fan as anyone, but lets face it: if Apple is going to charge a premium for its hardware for the privilege of running its software, Apple needs to do a better job of giving us "state of the art." We shouldn't let our appreciation of Apple cloud our judgment of technology.
And your argument that Macs must be good because we use them for 3-4 years before upgrading is specious. We wait so long because the technology doesn't change half as much in 4 years as it does in 3 for PC's. And we pay, on average, 50% more for a new machine than does a PC-user, so we have to get more use out of them.
Finally, I'll leave you with this: I was in a MicroCenter (PC store with a big Mac section) last weekend. I was playing with a Sony laptop (1GHZ Celeron, 128 MB, running that POS WinXP) and a iBook 600 MHz (with only 9.whatever on it (no OSX)). I wanted to compare form factor, boot speed, etc. The Sony PC was tiny like the iBook, and had a great form factor and a more responsive mousepad, but the ibook was nicer. But they booted up about the same speed. In fact, I think the Sony booted that resource hog XP FASTER than the iBook booted OS 9.whatever. Say what you want about our processor's and OS's superior design--unless we take that superior design and produce superior (faster, better, more stable, more productive, easier to use)product, superior design doesn't mean jack squat.
Apple has a unique opportunity to wow us with a complete product line overhaul and introduction of new products. We have already rewarded Apple for its ingenuity with our dollars. Let's hope that the posting on Apple.com are not ONLY hype.
