Jsut getting used to my Macbook. I like the fact that it boots up pretty quick. Its temperature can be quite hot, expecially when connected to the AC adaptor. Using iStat nano widget, sometimes it shows the CPU temp as high as 70-80 degrees celcius! Did a google, apparently this is not something unusual, with the Macbook Pro reaching 90 degrees celcius! Hopefully this kind of temepratures won't give any ill effects for my Macbook in the future.
Media card reader. You know, those 5 to 50 plus in 1 USB card reader. Apparently not all of them are compatible with Macs. The one I have is not even detected by my Macbook. Bought another cheap $18 one, and it is detected fine. Just a note: when buying something, make sure to read the system requirements, and try to buy things that explicitly say Mac support.
Another one for the wish list. Most PC notebooks can automatically set the brightness of the screen to a lower setting when using battery power (set in the BIOS). I don't seem to find anything like this on my Macbook. Sure, I can just reduce the brightness manually, but it's easier if the system can automatically do it based on the power source.
