My first post to these forums, so: Hello folks

.
I have been reading your comments regarding the PB-upgrades with great interest. And I can see few trends emerging. Now, as a disclaimer: I don't own any Apple-hardware, but I am interested in their offerings. I might buy some of their products in the future.
Now, that said, here are my thoughts about this situation:
What are the rumoured improvements PB is going to get? They are:
Speed-bumbs to 1.67/1.5GHz
Bigger hard-drive in the hi-end (100GB instead of 80GB)
Faster hard-drives (5400RPM instead of 4200RPM)
Faster vid-card in the hi-end (128MB of RAM instead of 64MB)
Better optical drives (supports DVD+R)
Bluetooth 2.0
I don't know about you, but I think those are fine upgrades! I espesially like the faster HD's, modern computers are held back by I/O-performance, not raw CPU-speed.
Now, there are some common complaints people have voiced here:
"They need to put G5 in there!"
Not gonna happen (not yet at least). In case you haven't noticed, G5 runs _hot_. If they wanted to put G5 in there, they would have to underclock it below iMac-speeds. And at those speeds it wouldn't offer any advantage over G4. Clock for clock, G4 and G5 are more or less equal. Hell, I wouldn't be surprised if G4 was faster clock for clock!
"But G5 has faster bus! The bus on G4 sucks!"
See my comment about CPU-speeds. Even with it's uber-bus, G5 is about as fast as G4 is, clock for clock. Some CPU's require fast bus to get good performance (P4 is an extreme example of this), whereas other CPU's do just fine with even slower bus (Athlon XP for example). Faster buses are (of course) a Good Thing (tm), but they are not such features that in order to get it, you must sacrifice everything else. Yes, you COULD get a G5 with it's uber-bus in PB. But the CPU would be underclocked so much, that in the end it would be slower than G4 would be! What good would that uber-bus do then?
"But G4 is _old_!"
So what? G4 is a fine CPU. Just because it's old does not mean that it's bad.
"But these improvements are hardly improvements at all!"
Faster CPU, faster hard-drive, bigger hard-drive, faster vid-card, better bluetooth, better optical drive. Those ARE significant improvements in my opinion!
Some people here need a reality-check! G5 in a PB? Maybe someday, but not today. Dual-core G4 in PB? Maybe someday, but not today. G5 runs too hot, and dual-core G4 is not ready yet.
Seriously, some people just can't be pleased!
P.S. If they do release G5-PB at the keynote, I'll end up looking mighty foolish
