First of all, for those who don't understand what's going on here, this topic was started in order not to derail another thread too much. If you want to see how we got to this, check

Secondly, dcolton, please try to use the quote tags. It makes your post much easier to read because it makes clear what you say and what I say. Thanks.
Now, let's try to look at your problems.
have never really tried logging out and back in. Having to do that is just as troublesome as rebooting in my opinion
I understand. Both are a pain, but it would help diagnose problems if I knew for example that rebooting solves the problem that "re-logging" doesn't.
They both should not be necessary. But, re-logging takes much less time than rebooting, so it's less painful.

You see, if re-logging solves the problem as well as rebooting does, it's probably a mem leek or a misbehaving app. If it doesn't it's much more likely to be bad hardware or bad prefs.
It usually starts to crash immediately. I have done a reinstall and installed applications one at a time so I could see if it was a specific program causing the issues. I couldn't really determin if it was one specific application.
OK, if you can't pinpoint it to a special app it could be the system, or the hardware. Did you do a real clean-install, i.e. a new system vs. just updating an existing system? Have you tried installing from another system CD instead of the same old one you would otherwise use? Did you wipe the HD clean before and update its driver?
Or it could be hardware... Did you unplug all peripherals apart from the Apple-manufactured mouse and keyboard?
The programs I use primarilt are Flash MX, Dreamweaver MX, IE (these three unexpectantly quit the most), Audacity, Warcraft III, Solace, and Dope wars.
Have you tried to see if using Safari instead of IE you can work longer w/o getting a crash? I'm just interested. I know there are certain things that don't work in Safari and certain sites that require IE, I'm just wondering.
I get a lot of unexpectantly quits and kernal panics. I seldmoly use any third party apps.
Unexpected quits do happen and most of them time the app itself is to blame. Not the OS or the user.
But the kernel panics are a really bad issue. They should never happen. When they do, it's 99% either alpha-level software or bad hardware. Since you claim to use only production-level software, I'd guess it's your iBook. Maybe its RAM, but maybe also just a peripheral (bad peripherals actually cause KPs often) that you need to unhook or, in the worst case, it could actually really be the board.
BTW, third-party apps are all the apps that don't come from Apple. The ones you mentioned like IE, Flash, etc. are indeed third-party. But that's just a side-remark.
Bad hardwarre could be the issue, but I doubt it. I recently had my hd replaced and it ran even slower. I didn't even take the time to install any apps it was so bad. I am actually waiting right now for a replacement computer. I would really like to have a much better experience with this one.
I do believe it is hardware. The problems you tell me are so serious and so numerous that I doubt it's just a bad pref file or a misbehaving app. Take the machine to a dealer. Try to explain as good as you can what goes wrong. Also tell them about the fresh system installs, that you don't use haxies, etc. Let them check the hardware. I'll be damned if they can't find anything at all.
