Interesting article, but their use secnarios don't apply to the typical user as well as the AnandTech article does.  
It's like a dual-core CPU: some people can really benefit, but most gamers are better off spending the same money on a faster single core or 2 un-RAIDed drives, especially since the chance of losing all data in RAID0 is almost doubled. 
(And their subjective results shouldn't be taken very seriously -- some people will say their speakers sound better with $100/foot speaker cable too.  They don't.)
		
		
	 
I see your points, depending on usage some people benefit, some dont.  I think Anand's article was to definitive, saying that there is no reason to run RAID on the desktop.  
Ive lost data running a RAID array before, and Ive lost data without a RAID array.  I did suffer hard crashes more often running RAID, and I killed more drives,  My guess is they werent able to handle the stress I was putting them under, nor the heat in my admittidly poorly cooled case I had.  Im in between RAID setups right now, but I am now in the good habit of backing things up regularly.  Warnings of RAID-0 failures are true.
I noticed an increase in speed with Cool Edit back in the day with my RAID array.  It wasnt purely subjective, because I could see in time how long it took to load certain sized files (over a GB back when 256MB of RAM was common), or how long it took to process them with filters (the HD was the bottleneck and not the CPU for alot of that).  I noticed an increase when I went to a 3 drive array and yet another with my 4 drive array.
Also worth noting from the link I posted was the difference you would see with a "real" RAID device instead of the ones tested by Anand.  I used onboard RAID, and when I moved up to the Adaptec 2400A I saw a huge difference with the same drives.
Worth noting, I did not see much of a difference in gaming, I loaded maps faster than others in online games, but Im sure more RAM would have made a bigger difference.
My point then, is that RAID does have its benefits for some people.  Its not a magic cure-all, but it certainly isnt as useless as alot of people here try to make it seem.
