IBM has also signaled that it's going to be much more aggressive in the future when it comes to taking on Intel and its x86 partners. In an analyst briefing, it pledged to beat any x86 system on a TCO (Total Cost of Ownership) and, if I heard correctly, also on a TCA (Total Cost of Acquisition) basis. That’s a big deal for Big Blue, which has never been known for bargain basement gear pricing.
