I started with an Intel G2 SSD in my MacBook Pro, then I added an OCZ RevoDrive PCI-E SSD to my desktop PC. My work laptop has an Intel SSD, and I'm considering picking a few more up for my servers at home and my media center PC as prices plummet. I can definitely say that they make a noticeable difference in perceived computing speed, and I'd never go back to regular hard drives if given the choice.
