My gut tells me its yet another costly mistake by Sun
Hmm - Sun has been profitable for 4 or 5 quarters in a row now. I believe that's their longest profit streak since the .com bubble burst. J Schwartz seems to be a man on a mission, and I personally like the direction he's headed with Sun.
I think we'll start loosing the mysql we've come to know and love.
I was more concerned about that when Oracle snatched up InnoDB and BerkleyDB. Yeah MyISAM is super fast, but there are a lot of web applications that rely on a transactional database engine. Oracle hasn't flexed their muscles and restricted use of those two db engines - but the fear of that has lead to the development of Falcon - MySQL's home-grown transactional database engine.
MySQL is great for web startups and Wordpress blogs, and it's also blazingly fast. I don't think any of that is going to change with Sun's acquisition. If anything - I think Sun will continue to innovate and improve MySQL by dumping massive amounts of money into R&D.
I gotta tell ya - with ZFS, Project Indiana, and now this - I gotta start looking at OpenSolaris. If you give me Solaris and all of the cool Sun goodies that come with that + the easy package management of a Debian based linux distro + the flexibility of ZFS + MySQL performance enhancements (as though it weren't already fast enough) and I'd have to seriously consider ditching linux in favor of Solaris/OpenSolaris.
In Schwartz we trust...
