    While I read this forum for information and to become aware of potential problems, I recognize that for every thread and post about a problem someone has, there are thousands or tens of thousands of people who are not having any problems. So, there are clearly not a lot of people who are having problems.

    Even if I did take problem posts and threads into consideration, what am I supposed to do, tally problem posts against no problem posts? Accept a 100 F temperature but buy something else if more that 3 people report temps of 105 F?

    I have both an 2010 MBA11 and a 2012 MBA11. Neither of them get hot. Do they get warm? Yes, of course the do. Duh. It's an air cooled computer.

    All Mac notebooks can get hot under heavy workload, but it's nothing to be concerned about. The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat. CPU Tjmax = 105C, GPU Tjmax = 100C on i3, i5, i7 processors. (Source: Intel) If you're not already using it, iStat Pro will give you accurate readings of your temps and fan speeds, among other things.

    Unless there is a rare defect in a Mac, most temps are well within the normal operating range, considering the workload being put on it. Websites with Flash content, games and other multimedia apps will put higher demand on the CPU/GPU, generating more heat. This is normal. If you're constantly putting high demands on your system, such as gaming or other multimedia tasks, expect temps to rise and fans to spin up accordingly. It's just your Mac doing its job to maintain temps within the normal range.

    It is also quite normal for your Mac to become extremely hot to the touch during intensive operations. The aluminum body transfers heat more effectively than other materials used in computer casings, so you will feel the heat more. This doesn't indicate that it's overheating and will not harm the computer to be hot to the touch.

    Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis). iMacs have 3 fans with minimum speeds in the 800-1200 range. They will spin faster as needed to keep temps at a safe level. If they're spinning up without increased heat, try resetting the SMC. (PRAM/NVRAM has nothing to do with these issues, so resetting it will not help.)

    The intake and exhaust vents are in the back of the computer near the hinge on all Mac notebooks (except the new MBP with retina display, which has intake vents along the sides at the bottom). The iMac vent is a slot on the back near the top of the computer. Make sure the vents remain unblocked to allow your computer to perform at its best.

    Your heavy tasks might not match mine. My MBA11 does not get hot regardless of what I am doing.

    Given the cost and the fact you can't upgrade the memory, get the 8 gigs.

    It depends on what you want to run. Certainly the faster SSD helps make page outs less noticeable. That said, if you do a lot of photo editing or run a virtual machine, then 8GB would help.
