Apple - Intel info

After some time saving up and deliberation, back in December i finally took the leap and purchased the Imac G5 20" with built in isight.

I only had my Imac G5 for one month and already it has been replaced by superior version comprising of a dual-core Intel powered chip. I am very happy with my Imac, but feel that when purchased I should have been advised by Apple staff of the upcoming release. If this was so, I would have waited one month until the release of the new Imac G5. Also the version of the Imac that I have '20" 2.1ghz', was only released on the 12th October, does this mean that this product is now obsolete after only 3 months on the market??

I imagine that there are many Apple users who purchased the Imac within the months of October to January, who now feel like they have missed out on something. Why did Apple upgrade the Imac back in October, only to upgrade it once again in December and also not to notify their cliental?

Do Apple now undervalue their customers and are simply on the gravy train??

what happened to the keynote video of yore explaining how power pc chips were so much faster than pentium chips?

are intel chips now the shiznit just because they are in apples now? doesn't all this mean that apples are now as fast as pc's that are already using intel chips?

Simpsons reference?
