Just in my department, the teachers and IT department are all like "Nah nah, those i7s and quadros aren't powerfull enough for xyz program" (autodesk like) when I have all of them installed at my home on a i5 and geforce setup, running of my ssds without problem.
Any people I've installed ssds for their main OS have never seen a fastest computer. My gf have a i3/4gb ram laptop, I've installed a 120gb ssd inside, and her battery life has boosted, it's as fast as my own computer for her student-esque task.
SSD "old-age" isn't as noticeable as a HDD.
For my perspective, the only downside of SSDs is the price, as the finite life of an ssd, for an average normal user, will be the end of the computer itself for different reason.
