I have never owned a Mac, and am considering buying one. My current desktop is over 5 years old and has an AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ 2.20 GHz. I am wandering if the processor available in the 13" Macbook Air is comparable: 2.13GHz Intel Core 2 Duo. I know this is not anywhere near the best performing Macbook, but the specs are otherwise better than or equal to what I currently have on my 5 year old HP Pavillion (250 GB HD, 2 GB RAM, etc.). I just do not know anything about the processors, and so I cannot determine if the price is worth the effort. Can anyone help?
