IMac 21.5" 3.06 GHz 4 GB Ram 500 GB HD

This is my third and best iMac that I have owned and used. It is faster than my last one with a much bigger memory. It came with the hardware ready installed so I was connected to the internet in less than 20 minutes after starting to open the packing. It has a wireless keyboard and mouse. I thought that I would have trouble mastering the mouse because the top is smooth without a trackball or track wheel. However the action came automatically. It started scrolling as my finger went looking for the trackball. Scrolling can be very fast or slow depending on your finger movement. I used to have trouble with Apple's previous mouse because the tracking used to stop. It was possible to restore the tracking but it was not always successful. This mouse has no trackball but senses the movement of your finger so should not cause any problems. kaw550redRead full review
