I have at last moved from PC to Mac, and I am not disappointed. My 21.5" iMac has a 3.33Ghz processor, 8GB RAM, 1TB HD and the better graphics card. It is fantastic.
Apart from being utterly stunning it is an uplifting experience to use, this machine is fast and powerful. I am a casual user of IT- I dont make movies or create music. I just want a computer to work- to be reliable, fast and efficient. I use it for loads of music, photos and surfing the web. It is effortless to use and navigate, and it is more intuitive than PC. I dont like the Mac/PC fight, Windows 7 looks very good too, but for the way this thing has been performing for me over the past week- and how it looks and feels- it frankly deserves more than 5 stars. My photos look absolutely stunning on the huge bright display and the stereo speakers are pretty good too. In terms of performance it is very fast- when I first turned it on it simultaneously downloaded 665MB of updates, over 3,000 emails and I didn't even notice as I surfed the web and explored my new system.
If you are thinking of moving over from PC, just do it. You wont look back. If you are already a Mac and dont want a laptop, what are you waiting for and why are you reading my review?
