HP's after EDS acquisition is a threat to IBM. And IBM's Open Source "love" will be tested.
With Sun in IBM's hands the competitive landscape changes significantly...
IBM's Linux support does not make so much sense anymore since it strengthens it's competitors HP and Dell, even Red Hat (Jboss vs Websphere).... One example: IBM has engineers in the System TAP team, while HP and Dell have none, does this make sense for IBM? HP and Dell kill IBM in the X86 server market, selling Linux servers without spending money on developing Linux... also Linux will not be needed to undermine Sun anymore...
Apache Harmony will have some problems, it will be hard to justify those IBM headcounts working on that project...(project that beside providing the java libs to Android will become useless to IBM). Apache Harmony will not be needed anymore to undermine Sun, IBM will have everything they need and it will not make sense for them to share it with their competitors...(unless they pay for it)
Sun's products that are not profitable and have no future will be shut down as they should.
Sun Industry influence was a lot larger than its revenue, IBM will benefit tremendously if they are doing the acquisition right. If I would be Cisco,EMC, Oracle or HP I would be worried about a Sun + IBM combo...
These leaks to the press are probably done to bring in another bid ... and frankly they should at least bring one to make the acquisition more expensive for IBM (like Garmin did to Tom Tom's Tele Atlas acquisition...). IBM + Sun is serious competitor...
