BTW - I/O was my point not processing power. When I was a kid... pre-pc we used to go to Radio Shack and load the cheapo computer with a basic script that counted to 10K. Well the cheapo computer could count faster than the expensive computer. So it was faster right.... well at counting it was, but it wasn't as powerful with actual math and calculation and it had a ton less memory. Same thing - sure a cluster of 300 PCs is computationally faster, than an E10K,but I stand by my statement... every job has a tool.

right - that's why there are so many high-end sun machines in the top500 supercomputers (top500.org). oh wait, um...there are hardly any suns listed.
hey - wait a second..what's this? a whole bunch of PC clusters in the top500? gee, that's weird... ;-)
</sarcasm>
the big-iron SMP vs shared-nothing cluster debate rages on, but high-end sun hardware, along with all the other monolithic smp machines have been trailing on price/performance for quite a while now. shared-nothing pc clusters simply dominate raw performance as well as price/performance - not to mention ease of provisioning.

that either as DSL can go faster then a T1 and significantly cheaper, but I haven't seen a way to combine the bandwidth for one IP. I've also seen DC3 connections from a few ISPs that are up to 20,000 a month. But still at a very poor bandwidth. I just don't understand what makes these different connections so special.
Perceived value :-) Kind of like Sun hardware. Sometimes people feel more comfortable when they have paid more, and the market is quite to respond for the need for this warm and cozy feeling.
For the bandwidth solution - the first thing that comes to mind. If collocation is too expensive, get as many cheap 1.5 MBit/s lines as needed with different IP addresses and use iptables + round-robin DNS.
Near-perfect uptime is expensive, the closer you try to get to perfect, and in many cases overvalued. I would venture to say that for a regular web application, if your site beats the reliability of their desktop , most of your clients will be satisfied. Once you reach a certain point, it is wise to spend your resources on the things that matter more especially when those resources are limited.
Like Sun hardware - come now... High end sun hardware kills PCs - On the other hand who wants to run the family site on an E10K. :) Every tool has a job.
