Spring M&A fever. Is something in the water?

I can't remember a week in recent history when so many deals were closed between technology companies.  Here's the list of what I know about. It's probably only a partial list.  Yesterday, Sun acquired the assets of storage solution provider Procom Technology for $50 million and then today it announced the acquisition of Tarantella for $25 million.  The company's president and COO Jonathan Schwartz explained the moves in his blog (see Sun acquisitions accelerate Microsoft interoperability). Today, IBM acquired open source outfit Gluecode.  Laplink, a blast-from-the-past company is apparently turning heads once again after it announced today that Microsoft has not only become and investor, but that it has licensed some of the company's technologies.  Novell has acquired Oregon-based Immunix.  Scansoft and Nuance announced a $221 million merger. eWeek has rumors of e*Trade's planned buyout of Ameritrade.  Sybase has acquired Avaki and ISDD.  Trend Micro announced the acquisition of Intermute.  And it's only Tuesday.
