Because they prefer to hold their own events and make announcements on their own timeframe.
 

Specificly, they said that having to have new stuff right after Christmas every year was not really helping them. It's not a good time for Apple to show things.

The difference is that all these other companies show future products. So they can get up and say "we're gonna sell this gizmo this summer!" So even they don't start selling stuff in January

But Apple likes to keep things secret. They like to say "Here it is, you can buy it very soon!" So they were getting forced into making new things in January which is not something any of these companies really want to be forced to do.
 
One of the reasons is that Apple's stuff would be lost among the dozens (if not hundreds) of devices that are introduced at CES.

No offense, but Apple rarely releases hardware that is at the cutting edge. The orignal iPhone 2G and (arguably) iPad are the only two products in recent history that were ahead of the game.

Everything else has traditionally been middling hardware Apple has built into their ecosystem. Apple relies on deep support and marketing to push their products. This message would be lost at a huge show where real hardware companies (as in companies like motorola who design & manufacture the chips, screens, and boards their products are made from) have dozens of new models and prototypes to exhibit.
 
does anyone know why Apple doesnt go to the CES and Macworlds no more ?

Because apple does not want to share the limelight with other manufacturers. By holding their own event after CES, they have a captive audience.
 
Apple doesn't want to sell out their ideas and give someone else a lead. Plus, Apple is very secretive. At least it will give Apple a few more months to get any issues with iPhone 5 fixed out.
 
Not in the same way Apple does. The trendiness and 'cool' factor is an integral part of the message that they craft in their ads and commercials.

No, most companies DO do that.

What's unusual is that many other tech companies don't. So Apple is more like the soft drink, car, and alchohol advertisers. It's interesting that other computer companies don't join them over there, but Apple is sitting with the majority of companies on that one.
