I used a SPARCbook back in 1996 for a business trip to Germany to install our search engine at t-online.de. The CFO of the company wanted to know who had this machine at all times because it was so expensive, around $20k USD.
It didn't have any usable battery life, if you tried to do any type of development, it would last about 20 minutes before it shutdown.
The many disk partitions made us get creative to fill the 1.2GB disk with data. We had to put files all over the place, and use softlinks get our software to work. This odd setup lead a sysadmin to "clean things up" one afternoon. He delete most of the OS in the process. He was really mad because he had to stay up all night to do a reinstall.
Wow, I forgot about that machine until this post.
