Yeah you can still buy them but they haven't been updated since like early Summer 2010, so you effectively bought a 2 year old machine. Sure even then they are still powerhouses...
but the debate here is whether Apple will kill off the Mac Pro completely or update it in next few months with a spec bump.
My two cents:
I've wanted a Mac Pro for a few years. I'm not a video guy but I game a lot (right now on a 2009 MBP) and I love the idea of the upgradability of Mac Pros vs other Macs and laptops of course. So I'd save up and get one if they update it, I'd consider a used one too.
Anyways I see a few likely scenarios:
- Like the iPod Classic which was last updated in late 2009/early 2010 they'll just keep the Mac Pro as it was Summer 2010 (might continue to offer upgrades on your purchase when buying for additional money).
- They could keep the design and overall form and just offer small spec bumps every few years (maybe every so often add that a new video card is preinstalled or something).
- They just never update it and let it die off completely and sell off the remaining Mac Pros circa 2010. They leave the iMac as the sole desktop.
-They eventually get to the tech point where they can pack the power, storage, and upgradability into a portable Mac Pro that is a souped up MacBook Pro a la upgradability meets Alienware. They kill off desktops completely.
- They move the Mac Pro power to a redesigned iMac and offer a super high end iMac. Although the only way the diehards and pros will use it is if it combines Mac Pro's power and storage with upgradability (which is something iMac lacks currently). But an all in one that also can be upgraded by the user for graphics, hard drives, other ports and cards...that'd be kind of cool.
As others have said I'm optimistic that Apple will keep the Mac Pro and upgrade eventually or turn the iMac into a hybrid of iMac and Mac Pro. Their relationship with Pixar means surely they supply Pixar with many of the computers and with all that intense video processing all the time, a Mac Pro does it. Plus Apple itself probably uses Mac Pros at its offices.
And finally, I kind of see the Mac Pro as the highest end of the highest end of Apple's computers. It's the most powerful, offers the most storage, and the most upgradability. Plus it costs the most and that itself makes it stand out as the top of the line in Apple products. Plus as a gamer, I could see Apple spinning the Mac Pro as a gaming powerhouse.
