why we need to buy a new computer ?

We need to buy a new computer as the needs come to us that the things have to be done more faster.Hence we go for the highest configuration with the newest processor. There is needs to have a good configuration to make the computer run smoothly and have a good time siting in the computer.

I think we need to buy a new computer bcz our old configuration is not good enough to run the new versions of the programs we usually use And also it doesnt support new OS or simply is not fast enough

Because we need to be update on the latest technology as the needs arises. Say, you want to add a new software on your computer, if you don't meet the minimum requirement for that software you're going to install on your computer, then it'll not work. That's why you really need to update your computer

The older ones you cant update as well. I have a windows 98 and its so hard to find programs for it. If you go to a store and try to buy programs its really hard to find it. It seems like its all for xp. But you could always just upgrade your old computer.

You would like to update your software. So, you need to update your hardware as well. One of the most causes of bad performance is to use new softwares with old hardwares.
