PC-BSD is good if you want to cut your teeth without having to climb out of common pitfalls to those new to the BSD world. I used it last summer and found it to be pretty good except there was some kind of bug at the time with flash which had a memory leak. Also, it uses a GPT which can cause problems later when you try to install another OS. After searching online I found a solution to dd the entire disk with /dev/null in order to wipe out the backup which sits at the end of the drive.
If you're ready for the real thing - go for straight up FreeBSD. They are extremely organized, you can go to one site for all of your questions, everything is well documented. They have pre-compiled third party binaries available known as packages in addition to all of the source which you can compile yourself. There is also a 'Linux compatibility mode' so that you can run Linux binaries.
Marketing blather. IBM is irrelevant unless you're an old business. Also, I was disappointed they didn't bring up the fact that Watson himself met with Hitler in order to help him automate the Holocaust.
How are they grandfathered in? Who else is going to solve medical research that isn't a big company like IBM?
Do you expect Medical research to be all hip n cool and use Heroku? Or should they choose IBM for their research into solving complex problems with their custom software and their custom blades?
