"Well, the auto and PC are competely different. "
Really, how many PC's do you plan on purchasing every year? Are you increasing those purchases? Eventually you will reach some cycle of replacement in the same way that the automobile did.
Just as the market will support X autos, it will only support Y PC's at some point in time.
"you 10 years old PC from 1990 may not be able to run most of today's sfoware program , so you need to continue upgrade. "
Yes, but will I need to upgrade as often? The PC of 1990 is not comparable to the machines now. The upgrade cycle will lengthen as speed becomes less of a concern.
"Pretty soon when the stream video compression technology comes to play , i.e video on demand, real time video broadcast through the internet, you will need more powerful PCs"
I can already buy TV add-on boards that will give me realtime video. Why would anyone put new video compression technology on a PC when it could be done more cheaply via an add-on card through hardware? Bandwidth is the real problem with video streaming at the moment.
"Besides, you will see more and more application on PCs come to play in the near future, and all these need powerful and modern PCs."
Name some for instance that the bulk of users might need?
It is beginning to look like the same applications are on the shelf as there were 5 years ago. Adding features to existing products is not the same as introducing new products.
The biggest sellers are business-oriented software, but these are becoming more network-centric all the time. Servers will need lots more power but the PCs on the desk will reach some point of diminishing return on upgrades.
Cheers,
