As a follow-up to my previous post, I've followed through and a Mac Pro is following along.
My decision to move now was spurred by a reminder last week about a temporary tax incentive (CCA class 52) the makes capital purchases of computer equipment eligible for a 100% write-off – but only if purchased before the end of January 2011 (that's today).
So I ordered one last night from the Apple online store – a refurbished model, actually. Though this will be my first experience with an Apple refurb, the option was a no-brainer: selection is good, prices are generally hundreds of dollars less than nominal, and products carry a full warranty and are eligible for AppleCare.
The machine is a 2.8 GHz quad-core "Nehalem" Xeon with ATI Radeon 5770 (1GB) graphics, plus the usual array of bells and whistles. I'm looking forward to kicking it in speedy style with the latest Xcode and iOS toolchain, and Aperture on the 27" display.
