Yes, I agree. I'll caveat my original statement by saying this; I use Windows (work machine), and I'm using the SSD's they gave me, so they may not even be good ones.
That said, I can come nowhere near the performance of a video where some guy wired up a bunch of SSD's, then opened every microsoft office application at once and they just popped up on his screen. Some crude timings below (in seconds; time to open from the "Start" menu, till the hourglass morphs back to an arrow):
Word: 3
Excel: 2
Outlook: 5
OneNote: 1
PowerPoint: 2
Emacs: 2 (had to throw that in)
Now, you may be saying "DUDE! That's awesome!" and yes, it is, compared to platters. But it's not instantaneous, and as soon as your context readjusts, you still notice the startup time.
