Hi, i am a uk based designer, I have seen the light and decided to move on to Apples' machines for business. I have decided I will be going for the baseline iMac 27 and the MacBook Air. I won't be using the air to create designs on. I just find myself increasingly on trains and i quite like the look and feel of it. I have a look at the Macrumours buying guide which says only buy if I have to for the iMac and do not buy for the Air. Any ideas how long I will need to wait? I can easily wait 3-4 weeks but think any longer than that and I'm going to have to get something. Regards.
