Rod, the evidence is direct from the mouth of Matt at Rundle Mall Next Byte, and the quote he has given was ball park figure of 1g to replace. I have no idea of the cost of these things, I was equally as baffled as to why the logic board would cost approx 2g to replace. From my PC days you can pick up a mother board for about 100 bucks.
$3000 buys a lot of iMac, true: specifically it has bought me:
2.66GHZ QUAD-CORE INTEL COREI5
4GB 1066MHZ DDR3 SDRAM - 2X2GB
2TB SERIAL ATA DRIVE
ATI RADEON HD 4850 512MB
8X DOUBLE-LAYER SUPERDRIVE
APPLE MAGIC MOUSE
KYBD(NUM) & USER'S GUIDE-X
COUNTRY KIT,IMAC 27-INCH-AUS
Not included there is Apple Care (you bet I bought it this time!) plus the remote (which for some reason only Apple understand, it is not shipped as standard with iMacs anymore?)
I haven't bought the iMac to "match" the capabilities of the Macbook Pro, I've bought it as a desktop machine and hence went with higher specs to crunch the data I am processing more efficiently at the lack of portability. Since you mentioned it, my specific daily requirements are as follows: I am a photographer for a music magazine. I also shoot freelance including weddings. Typically I am processing RAW files in Lightroom (12mb each approx) (anywhere between 200 - 300 shots) exporting those as uncompressed tiffs (between 40-60mb each) and then opening ALL of those in photoshop for final processing, watermarking, downsizing etc etc.
For the record the Macbook Pro did these tasks fine for the last two years (although it would take quite a while to open all the tiffs in photoshop so i'd usually go grab dinner at that point). Scope my work at my site:
http://www.bjwok.com perhaps someone would like to commission me for a shoot to make up for this loss? 'll travel anywhere in OZ if booked early enough 🙂
The Macbook Pro is going to cost 1g to just fix the left I/O board, then on top of that I still need the logic board/graphics card repaired. (2g) Again, this information is from two separate authorised Apple repair centers (Next Byte, Rundle Mall & Mac Alert, South Road), so yes, including the cost to buy the Macbook Pro originally and the cost of repairing it, plus the cost of the iMac, Apple have me down for 8g. I don't think that's guilding the lily at all, it's just the amount of money this will set me back!
