It's always fun to speculate about IPO's, mergers and acquisitions. In the tech industry it happens so often it's hard to keep track of who bought who and how long ago it was.
My current train of thought on the topic surrounded the recent news of CoreSite. CoreSite is a Carlyle Group company, which as I mentioned before is a HUGE global private equity company. I wondered if CoreSite would do an IPO in the near future. Carlyle invested in Equinix in 1999 -- their site says "acquired" in 1999. Equinix then raised $240 Million in their IPO a year later.
Some other interesting ones I have seen a few times:
Cisco has made lately, there could be some acquisitions by the other big players to get deeper into the networking market:
I refuse to believe that Cisco would buy EMC, but do think they could/should buy NetApp. Or maybe Isilon Systems?
Either HP or Cisco could by F5
All speculation -- but the tech industry M&A activity does seem to be picking up.
