Hello...so forgive me if this is in the wrong section but I am contemplating an iMac among other Apple systems nad need some advice. I spent nearly an hour in Best Buy yesterday trying out iStat pro and seeing how it responded to various tasks on the computer - flash video, HTML5 videos, rendering a movie in iMovie, etc. Part of why I'm posting this is that I didn't get satisfactory data to help me. For example, on the iMac, it was the only system that had the ambient temperature correct, which I would have guessed to be in the upper 70's. All other systems in the store that I put iStat on had the ambient temperature in the low 100's. All temps are in fahrenheit, too. The iMac HDD temperature stayed a relatively constant 130F or so. Now I've read enough reviews were people were freaking out about temperatures and I've heard enough of "that's nothing to worry about" to gag me. I've read some technical articles about the inverse relationship between HDD temperatures and longevity and the relationship seems clear and it's not good 130 F for the HDD under no load was high compared to the MBP and MBA whcih ran at 85 and 99, respectively. My problem with the MBP is the only one I can do is the 13" but I have a problem with the screen resolution being so low. If only I could do the 15" but I can't right now. I was very close to doing the MBA but the lack of a gigabit ethernet port is a deal breaker for me. Still trying to get an idea of how much of a hit Internet speeds will take by using a USB or Thunderbolt adapter to cable connect Internet. I thought about the Mini too but it has another downside that is why I passed on the Air - dual core processors. I probably have to do something in the next 6 weeks so depending on when they do the refresh, I may or may not have time to wait. I use an iMac for work and one thing that bothers me immensely about it is the reflection on the screen. That's one advantage to the Air or Mini were it not for the other aforementioned issues. Sorry for the rambling nature of this post, just trying to make a decision. Nothing stands out so I know I'm going to have to compromise on something - just not sure where it should be.
