My PowerBook G4 (OS X 10.6.8) is classified by Apple as Vintage and Obsolete!

I'm completely stymied. Less than 8 months ago, my PowerBook was shipped to me new. Now, I can't get online info, because my laptop is considered "obsolete and vintage"

What kind of rationale is at play here? How can it possibly be obsolete already?

I paid an extra $200 for Aperture, but I can't use it - there's no SD Card slot! My crummy old $300 Acer had a card slot, and $1400 doesn't get me one now? I can't replace my long-lost camera cord, and can't afford a new camera. So I can't upload photos and worse, I have a few hundred photos I really need that are stuck in Windows Photo Gallery on my falling -apart old PC.

I have to admit I'm not the brightest bulb on the computer-savy tree. The answer may be embarrasingly obvious.

Anyway, can someone please explain in simple language (like, pretend you're explaining it to a class of third or fourth graders - seriously)

Also, why would the mouse pad stop clicking properly? It takes a great deal of pressure to get any response. I dreamed of getting a Mac, but frankly, my cheap old PC with six keys missing did a better job in terms of basic function.

Thanks a lot for letting me rant! Any help will be greatly appreciated.
