I think the new Mac Pro episode will resemble the iPad one - lots of "ohemgee it's like just a bigger ipod, lol, how stupid do they think we are, kthx?" reactions, when in fact this product will probably push a new paradigm shift in the way workstations are built i.e. moving away from the plastic pieces of shit ubiquitously sold now. Seriously, I dare you to look around a regular "PC customization" website e.g. [1]. Apart from Razer and maybe Alienware nobody has even tried to really innovate the workstation landscape. I remember when I was building one of my first desktops with my dad - 20 years ago.
A final thought: Apple has a million flaws (mostly software and systems, grr), but they didn't get where they are for being stupid or for not understanding the market, so at least give them some fucking credit.
