Comparing Your Existing PC with the Mac You Want
Before deciding which Mac to buy, you need to figure out what is on your existing computer. You’ll want your new Mac to have at least the capabilities of your present computer, plus lots of room to grow. You may know some of this information and much of it may be on the sales receipt or the original box your computer came in. Of course, if you have added options and peripherals, that info may be out of date.
The easiest way to get the information on your current configuration is to ask Windows to give it to you.
Choose Start→My Computer.
The My Computer window appears. You should see a section labeled Hard Disk Drives. If more than one drive is shown, start with the drive labeled C:.
Select your C drive and then choose File→Properties.
The Drive C: Properties window tells you how much disk space is used and how much is available.
Make a note of the drive’s total capacity and how much of that is used space.
The numbers to the right, which are shown in GB (gigabytes), are all you need.
When you’re done, click Cancel and then repeat this procedure for any other hard drives shown in the My Computer window.
At the bottom of the My Computer window, you should see the Control Panel icon appears
Click the Control Panel icon.
Alternatively, you can select the Control Panel directly from the Start menu. When the Control Panel window appears, double-click the System icon.
In the System pane that appears, make a note of the following:
Operating system (for example, Microsoft Windows XP)
Edition (for example, Home)
Last installed service pack (for example, SP2)
Manufacturer and model number
Speed (for example, 1.8 GHz)
Amount of main memory (for example, 224MB RAM)
