Really, I agree with the above. Yes, bummed, but com'on. You got a really nice machine which could easily satisfy your needs. I bought a 14" iBook last November and still hasn't regretted it. Yes the MacBook Pros and MacBooks are bitchin', but everything is still Rosetta, whining, mooing, heating/cooking issues are imminent as well as bad backlight bleeding on some of the 17": No, these laptops are not "finished" yet in my opinion, they're still on the beta table.
If everything goes well in a couple of months, you could always save up for a fully functional MBP for home use and use the iBook as a great transportable and very capable notebook.
I know I am gonna buy a 17" for the screen space (I am fed up with only having one document at the front at a time and exposéing all the time) and use my 14" as a transportable studying computer. I love the mac laptop line (keyboards and touchpads are soooooo nice) and wouldn't get a desktop until old age anyway.
Be happy with your new discontinued iBook and use it well. Just be happy about not having any problems yet 🙂
