Guys thank's for all your replies, supportive or not.
To clarify, I came to Macs because I couldn't believe what a total pile of junk Vista was (is).
I came believing the hype, that this OS just works. I believed all of the Mac/Windows ads. I was sold.
I purchased a MBP on the day Leopard launched. I work for an airline and the MBP was just too big and have for my travelling needs. I took it back and swapped it for a MB. I was quite happy with that, but as soon as the MBA was released I sold the MB and purchased the air.
I can live with 1 USB port (just) and like everything about the air. What I cannot stand, is out of the blue the fans will start to run at full tilt when I am doing nothing. At the moment, all I have running is this forum. Maybe in 10 minutes my fans will be at 6900rpm or maybe they won't. It's that simple.
Yes I like Leopard but almost everything I do with is seems to generate bugs and crashes somewhere. I can't remember the last time a Windows machine ever fully locked up requiring a total power down. My Air has done it several times since owning it. Applications quite often crash. I can live with that because I believe Apple fix things quickly. I purchased 4 iMacs a couple of weeks ago (for my other business). They are great, don't really crash and I hope that the several bugs I have encountered get fixed in 10.5.3
I will take my Air back to the store, but like I have said countless times, I am convinced it is not faulty. I just think it is a poor design. To all those people to are having a go at me because I am complaining about the noise of the fans. Have you ever heard the Air's fans running at 6900rpm when all you are doing is say, typing a word document? It sounds like the machine is on its way to destruction. If it is normal to do that, than I have purchased the wrong product and it is not for me.
Re my comment about about the Air being quiet as I am typing this.....Oh here we go again, the fans are starting to speed up like crazy now currently 4200rpm and increasing.
I will sign off now because I can feel the irritation coming back.
I think the USB Ethernet is the culprit.
RPM 4900 now. I guess one core will shut down in a minute and then the thing slows to a crawl.
GRRRRRRRRR!
