Basic systems are essentially appliances. For the most part they're
all standard components and they all work the same. Although eMachines
seem to have a propensity for failing power supplies, which tend to
take the processor or motherboard (or both) with them.
Dell often has very reasonable systems, complete with 17" flat panel
monitor, for $450 or less with no rebates required.

That's baloney. Any checking will happen much faster than your wire
speed. What's gotten slower is the rendering of the "rich content" that
many sites feel are so important. My favorite source for PC components,
NewEgg.com, is painful on my old 800mhz laptop.

If you don't run a virus checker, how do you know?
That's not just foolish, it's stupid. There are free AV products out
there, some of them very good. I use Avast! on all of my home PC's.

And you don't use IM? Hopefully you at least keep your OS and apps
updated with the latest patches. Even Mozilla/Firefox has had it's
problems, and some exploits were independent of the browser used.
Even only visiting sites you trust isn't good enough -- there have
been several reputable sites responsible for spreading infections
because the site serving their banner ads got compromised, and they
were serving infected content with the ads.

You know, there's really nothing to relate Internet activity with disk
activity. And hard drive performance has almost nothing to do with the
performance or capability of a system.

While I agree that they're unnecessary and mostly pointless, the
system tray apps don't consume cycles. They do consume memory,
however. Removing them helps, but "modern" OSes consume enough that
taking that step isn't much by itself. Memory is currently cheap. You
can significantly improve performance just by adding memory. I
wouldn't even try to run XP with less than 512M of RAM, and generally
prefer 1GB.

They don't consume cycles, but they do take memory. Most service
processes live in a constant blocked state until they're actually
needed.

Go study International Law and politics. Most of the phishing and
virus development and operations happens in place like Russia,
Romania, Korea China, etc. The Russian mob is very big in funding
virus R&D.
If you really care about viruses and spyware, don't use a Windows
system. Get a Mac, or a Linux system. Nothing is 100% secure, and
there have been reported security issues with Macs, but I can't think
of a single published expoit targeting them.
