*whistles* If you have not tried out a SSD laptop or desktop then you're 
in for a big surprise.  Especially if you multi-task at all or work with 
a few thousand small files.  It can make even a 10k RPM SATA seem slow 
when you try to do multiple things at once.  Boot the machine up, start 
doing work while things are still loading up.  Which is a situation that 
would bury a 7200 or 5400 RPM drive in seeks.

After having a 10k RPM SATA on the desktop for a few years, 7200 RPM 
seem slow and 5400 RPM drives seem glacial.  The SSD in the laptop can 
make the 10k RPM SATA seem slow in comparison.  It's the difference 
between 200-300 seeks/second for a mechanical and a few thousand seeks 
per second.

The main downside right now is cost and how big of a disk you can 
afford.  SSDs are wonderful, but still in the $1.50-$2.00/GB range. 
Better then it was, but I was disappointed with Intel's 25nm pricing.
