Re: Clock speed

I'm not saying it's not true--it's just damn hard to believe when a P4 has double or more the clock speed, DDR RAM, and a 533 MHz system bus. I really, desperately, want to buy a Mac for college, but I'm running XP on my home PC now, and I have to say I'm impressed.
I'm still definitely leaning towards Apple, but it's getting harder to maintain my convictions. It will be difficult to rationalize (personally, but even more so to my parents) buying a $3000 PowerBook, when for $2500 or less I can get a laptop with twice the apparent speed, and when the only advantage is "I like Macs better."
Figure on G3s equaling a P3 of 1.25-1.5x the clockspeed (this is a very rough guess), so the 700 ibooks are in the 750-1000 MHz P3 range (that's the mobile P3s), faster on a few tasks (floating point heavy ones). G4s are moderately better than G3s, except that on certain very specific tasks they can be anywhere from 2 to 10 times as fast. Figure a dual GHz is about equal to a P4A 1.6-1.8GHz when it isn't using Altivec much, and maybe a P4A 2-2.2GHz when it is (this assumes a well threaded program, and is a very rough guess). It's mainly memory limited, so DDR should help a LOT. Currently, for most tasks, the P4B 2.53GHz is the fastest desktop chip (fast ram, high clockspeed, crappy design), and the AthlonXP 2200+ is the second (good design, moderate clockspeed and ram). G4s and G3s are slower (low clockspeed, slow ram, but awesome design [Altivec specifically]), just not by nearly as much as it seems (they're low clockspeed and have slow ram, so it's amazing they do as well as they do).
OS wise, the Mac wins hands down. XP is a joke. It's ugly, clunky, insecure, included programs are much worse, doesn't support Java without a patch, and misuses eye candy even more than aqua (in OSX menus fade out, in XP they fade in, see the problem?). OSX is awesome, it just needs the hardware to back it up.
Basically here's how it matches up:
Speed: PC
Hard Drive: PC
Optical Drive: Mac
Networking: Mac
Ports: mixed
Stability: Mac
Appearance: Mac
Usability: Mac
Programs: PC (although their are a few great mac only programs)
Lifespan: Mac
Price: PC
Peripherals: PC
Customizability: PC (it's easier on a mac, but there's less you can do)
My recommendation would be to wait and see if Apple gets it's hardware back up to date. If they don't go build yourself a Hammer system, if they do, get a PowerMac.
