hola
i bought my Mac Book (black) about a year ago.
(my friend works at Apple so yeah...

)
i think OSX can take a bit of getting used to but once you do, you will see how far ahead it is of Windows. i personally will never go back to PC. you can run parallels or boot camp to run any windows app you want. no viruses...! boots up in an instant, runs like a dream if you know what you are doing. did i mention no VIRUSES, i can't emphasize this enough
the issue of it heating up, particularly the black ones...i suggest taking it to the Apple store near you. i'm pretty sure they were having issues with the fans on the Mac Books.
MUXU, i'm pretty sure when you set up your IPOD. it asks you if you want ITUNES to update the ipod automatically each time you sync or if you want the user to do this manually. usually ITUNES will recognize a different IPOD connected to the MAC, the name will appear (MUXU's Ipod) is connected...do you want ITUNES to automatically sync...
the thing i do is transfer my friends music to my MAC, via their network, or d/l it on my own. remember MAC aren't prone to viruses so this is generally safer then on PC. or you can always download via ITUNES.
this will be a M4P file type instead of MP3 which you are used to....so...you burn the files you want onto a cd and then rip it back using ITUNES as an MP3 file. bye bye protected file
you can always just walk into an Apple store and ask them just about anything...just remind them that you don't speak tech lingo, and to explain, explain, explain.
