People that don't see the benefit of SSDs are usually single application users. If all you do is load up a game or app that loads most of the code into memory anyway, an SSD will probably not be fully utilized.
		
		
	 
It seems like at my home computer when I use one or two intensive apps at once such as when gaming or whatnow it doesn't matter.  I can see how it may help out with my work laptop since I open about 30 random word and excel documents all the time and it crawls at times.
With my home computer, I have a much more powerful processor, more memory and a faster spindle drive to begin with.  I just open up whatever I need and leave everything open.  
As far as installing/moving files when trying to use the computer, I have 2 drives that I load balance when I do these things anyway.  If I download a large compressed file it will be on drive 2.  It will be extracted on drive 2 but installed on drive one so there isn't really much slowing me down there to begin with.  
	
	
		
		
			Try installing some large apps with your hdd then try to open a browser or computer management or control panel while waiting for the app to install. Happy hour glass yay. Now try and zip 5 gigs worth of 100k or smaller files, or compare a few hundred thousands files for backup, or move or copy your music collection... Happy 151 hours remaining progress bar. Gotta run chkdsk? Come back tomorrow!
		
		
	 
This confuses me.  What kind of slow ass hard drive are you comparing it to lol.  I install large (6GB installer) programs all the time and I have no problem working on the computer while I'm at it.  Sure it takes longer to open photoshop if I feel compelled but the start menu should not take longer to load.  As far as moving files, desktop hard drives are not that slow to begin with.  It took me 12 mins to clone my boot partition going platter > SSD, that's about 50GBs in 12 mins averaging 71MB/s.  I could get it done in probably 4-5 mins going ssd > ssd but I digress.
There's been talk of moving files around but afaic that is not the reason for ssds.  I thought it was for the ultra low seek times that made loading the OS files so much faster.  The problem with that is.. how often do you have to reboot your computer where that actually makes a difference?
	
		
	
	
		
		
			There are rare examples where a SSD doesn't help that much after loading the OS, but that just means you don't do much with your machine.
		
		
	 
I'm having a difficult time coming up with a usage where you are constantly pulling the same files over and over.  I guess if you load photoshop with a thousand addins all day long... but then just leave it open??  SSDs are not large enough that you can pull that much data off of it.  Chances are you would be using a network drive for a lot of files for work anyways.  The only things that matter are core windows components and few applications.  Everything else is moot as they are not on the ssd.
