New from Apple: A new server and a new powerful workstation

Apple unleashes new Xserve and new Mac Pro.
2 very powerful choices going to fight with PC manufacturers like HP and Dell. Why?
Apple is known for making good machines for people working on multimedia and design. And it looks like they don't want to forget that space of the market and let it to their competition. That goes for the Mac Pro.
Xserve is making a change: unlimited user licenses including in the price of the server. That makes me think that Apple is thinking on becoming a good alternative for Web servers. The Mac OS X Server sounds interesting because it tries to compete with Microsoft by including a Calendar server named iCal Server like part of the OS; Microsoft offers that with Exchange Server. They also include Wiki Server like an alternative for Blog and Wiki hosting, something that could become competition to Windows SharePoint Services.
MacWorld starts in one week.
