Was there a need to create another thread pal? Are you a professional? The latest mac out are the latest iMac you can buy. If you have waited this long for a newer model then just wait.
This forum is like groundhog day before things come out. Some people are still waiting for Mac Pro, thinking I should of just bought it last year. You cant keep chasing latest. If you are casual user current iMac are more than enough. You're money though.
