I see your pricing, now let me make another one.
Using your Mac
# 2.66GHz Intel Core 2 Duo
# 2GB 800MHz DDR2 SDRAM - 2x1GB
# 320GB Serial ATA Drive
At... 1,499
Against my PC
Intel® Core™ 2 Duo Processor E6420 (4MB L2 cache,2.13GHZ,1066FSB)
3GB Dual Channel DDR2 SDRAM at 667MHz - 4 DIMMs
320GB1 Serial ATA 3Gb/s Hard Drive (7200RPM) w/DataBurst Cache
At... 1,109
As you can see, while my PC has less processing power, if only slightly, it has more RAM. Also upon further inspection while my PC's monitor is an inch smaller I don't think that matters all to much.
Your up next.
