My main PC is around 4 years old now. This is the time to replace it.
I am considering to an AMD PC. This is because AMD dropped the CPU price. AMD Athlon™ 64 5200+AM2 Processor Retail Dual Core AM2 is around AUD$170.
I was an oversea student. My friends around myself at that time, most of them got a Laptop. I was wondering why?!!!! Laptop is near double price as the same level of the desktop.I have talked with them for this question. Most of them bought their Laptop from their home country so that they use computer at the first day in Australia. Moreover, they didn't know where can buy computer in Australia when they were new in Australia. Thus, the best choice was buying a Laptop in their home country.
Well, I bought a Desktop in Hong Kong and brought to there, because I think Laptop is cost too much and hard to upgrade. But two years ago, I bought a Laptop in Hong Kong too. At that time, I am already working as Programmer. I need a new computer at home and in some situations, I needed to bring my work between office and home. Thus, this is good to have a Laptop.
I bought a Laptop for good reasons.
