I have a 64GB SSD in my laptop and I love it. Upon a clean Ubuntu install my system booted in 28 seconds. After tweaking my system some I got my boot time down to 12 seconds.

I tried opening OpenOffice after watching this video and found that OpenOffice writer opens in less than 1 second and opening all Office applications except for database and impress takes less than three seconds 3.

The difference between SSDs and HDs is definitely noticeable.
