you should all try Mac OS X v10.6.1, i've had it for about a month, no problems what so ever, works smoothly, quickly, efficiently. THE best laptops and desktops on the market
Couldn't agree more. I made the switch to an iMac just over 1 year ago and I'm more than happy. OSX just runs constantly and without any glitches. I only reboot my iMac about once a month. It handles large video files without disk thrashing unlike any version of Windows and any kind of image manipulation is a dream.
I run Parallels which allows you to run Windows on an iMac at the same time as OSX. It's totally seamless in that you can hide the windows task bar in coherence mode and the whole system is still a Mac in essence but you can run Windows apps too. If you don't want to run Parallels then most applications are available for Mac so that's not a problem. Games IMHO are best left for consoles, I have a PS3 and Wi in the lounge which are fine for my gaming needs.
