Save your money (and get a free leopard)
I did this when i bought my powermac last year. It makes sense if you are going to buy a machine over 2700$. first purchase an Apple Developer Connection membership for $500US (~$550 canadian) then use your 1 system discount to buy your mac. it will be cheaper!
Eg. In the pre-intel powermac days. The quad was $3899 retail and $3099 thru the apple developer store. also, all the accessories (memory, hard drive, airport, bluetooth, wirelss kybd/mouse, eveything) is cheaper to BTO.
After an initial look at the new macpros in the developer store based onthe
standard config doesnt save you anything but you get the idea...
retail store = 2799
developer store = 2239 (+550 for ADC) = 2789
for the 3GHz its $750 less
retail store = 3759
developer store = 3007 (+550 for ADC) = 3557
the more you customize it the more the price differential grows, savings on displays are substantial as well.
its cheaper by $200 with the adc PLUS you get all the leopard previews mailed to your door, plus apple gives you CD/DVD copies of all supported operating systems. Plus you get access to all the developer tools and many other pieces of apple software. Plus you get developor mailings every month with the latest and coolest tips and tricks. And the one thing I know will sell it for many of you... you get a T-SHIRT! ...and a cool BOX to put all that crap they mail you!!
Its really a good deal and Im surprised apple doesnt promote it more!
