I'm currently on a MBP 15" (spring '07) and have changed fans once. Everyone is talking about performance on blogs and forums but I haven't found much written about how loud the new MBPs are. To buy a new laptop is a long term commitment. I'm pretty annoyed with my current MBP since its so loud. The fans are spinning almost spinning on max RPM the whole work day (running a web browser + photoshop or text editor on an external 23"). Is the i5 a better choice in the long term since it is slower and not as hot as the i7 (I'm guessing here.. no facts). I care more about noise than performance. What do you think? btw. I'm going for the SSD 128 option.
