I'm emailing you from an SSD based machine at the moment.
I don't need a 120 Gig drive on my workstation. I remember running SuSE
5.1 on a 500meg hard drive. We really need to just slim things down
and use smaller machines. I call this the Walkman Revolution.
The Boomboxes needs to die and SSD is a good part of changing the
mindset that people have about computers. They need to be smarter
designed, small and cheaper.

Yeah - for backup systes that the government makes you do.

You must be a stupid engineer then, because politcs and technology have been attached at the hip since the 1st dynasty in Ancient Egypt. I guess you missed that one."
