OCD has nothing to do with wanting your apps to run faster. When your job and paycheck rely on actually using apps like avid, fcp, photoshop etc to get clients what they want faster, having your apps run as fast as possible is more important than waiting for them to boot up. Notice what the OP started this thread about: photo and video editing, not browsing and sending emails.
I'm not knocking those who got SSDs, like yourself, no need to get defensive.
But wouldn't you agree that actually using an app (rendering video, editing photos, formatting a document, mixing tracks, etc) is more important than waiting for it to boot up?
Sure, SSDs are the future of computing. HD's are the bottleneck of current systems.
But if I can't put a terabyte's worth of photos, video, and sound files on a drive that's as fast and solid as SSDs are, there's really no point. For those that don't need that much space, sure, it makes total sense to go the SSD route. Like you said, if all someone is doing is operating a browser then yes, SSD's are the best way to make your computer feel as speedy as can be. But for a $650 premium? Your browser will pop up faster. Woohoo. Chrome pops up in a second on my four year old macbook pro with 2 gigs of ram. If my photo libraries, video files, and redering could all happen with that speed then sure, an SSD would be the best possible investment I could make for my computer.
To the OP: for those looking to push all four cores to their max so as to make their workflows and processes operate as fast as possible, the current price and capacity of SSDs aren't worth it.
