Having been a PC user since 1986, I switched to Apple. My first PC was 4 Mhz with no hard drive. I built my own computers over the years and became fluent in all versions of DOS. However, with each passing year, I became a slave to the whims and bugs built into Windows. I got tired of upgrading to new user-hostile operating environments and Vista was the proverbial straw that broke the camel’s back. I chose the MacBook over the MacBook Pro because for the price, the MacBook seemed that it would serve my needs. I have not been happier. I upgraded to 2GB of RAM and the 200 GB hard drive. My order was shipped one day before the 2.0 Ghz CPU was upgraded to 2.16 along with an upgraded hard drive. I contacted Apple and they offered to send me the newer computer or refund $300.00. I chose the refund because I usually buy last year’s technology to save money. I have not been disappointed. No freeze-ups, no problems. The OS is very intuitive. No problem is using my old files with the Office for Mac software. I paid extra for the three year warranty because I am not a gentle person with computers. My next computer will be an iMac.
