Hi In November i placed my order for 27" i7 iMac to replace my 24" iMac C2D to have Quad-Core CPU, really better performance, a bigger, LED backlit and better screen! Now, unfortunately, I do not know what to do: I just sent back my fifth iMac with yellow tint, I asked for a full refund. So now I'm searching for a solution to replace my iMac with other Apple computer to have similar performance and Screen. Mac Pro is the only machine with comparable iMac i7 performanche but the problem is the screen! There a good 27" with 2560 x 1440 resolution with IPS technology? I considered the case to keep my MacBook and install a SSD drive for better performance. What do you think i can do? If i hold my actual MacBook Pro I can only spend 2300 $....if i sell the MacBook Pro i Can spend 3000$ What' s the best solution? P.S. I use computer for software dev (obj C), using VmWare or Parallels, using Aperture (with RAW file, terrible experience with my actual MacBook Pro). Thanks !!
