I have two PCs, one of them is 2 years old, and the other is a year old. But I'm using my laptop most of the time. My PCs are there running, downloading and uploading things.
2 months old, bought a mac, my Windows OS laptop was crashing so much that I threw it out the window!
My Home PC is 4 years old Intel 2.8 GHZ dual core, 1 GBs of RAM, and total 500MBs of harddrive My Office PC is 2 years old The same spec as above but it's AMD with less hard drive space .
