Your post all seems to be very consumerist. IBM sells servers. Apple does not sell servers. IBM sells their own server hardware. IBM dropped their x64/x86 servers recently.
Apple makes consumer hardware, IBM makes expensively marked up enterprise hardware.
IBM makes TERRIBLE software, apple makes shiny consumer stuff, the absolute most that will come out of this is sametime and or notes getting a small bit more attention from IBM on iOS products. Most of IBM's crap is a thinly veiled customisation on top of Eclipse, it makes me laugh thinking about how that will translate to an iOS device. IBM's server side software, while marginally better - what apple hardware is that going to run on?
IBM clients couldn't give less of a hoot about samba shares in OSX. This news will have approximately zero effect.
