I have a few questions about buying a used iBook that i'm wanting to take with me to europe next year on exchange. The main purpose for the iBook will be holding my digital pictures, holding music for my iPod, and basic homework (wordprocessing, slideshows, etc. I'll probably buy microsoft office for mac). Now, chances are my host families will have computers, but i'd personally rather have my own so i don't have to bother using theirs, plus i don't want to fill their hard drives up with my multiple GBs of pictures and music (and then have to worry about copying it over to a new family's computer every few months). I'm going to be new the mac world, and i figure i could buy a cheap iBook to get my feet wet with, and then maybe get much faster new Intelibook in a few years once i graduate high school. So, my question is, am i losing much by buying a g3 iBook? I've been looking at them on ebay, and it looks like i can get a 12in. 900mhz one with a 40GB hard drive, 384 MB of ram (I would upgrade to at least 512 mb or more), airport card (is there a difference between an airport card and an airport extreme card? This one says "801.11b"), iLife 04 and OSX 10.4 for $575.00, buy it now. Is this a good price? It says the battery holds about a 2 hour charge, will a brand new battery from apple work on this computer even though its not a g4? Also, if i buy office for mac and install it on this computer, will i be able to install it onto a new computer once i upgrade to an Intelibook after high school or will i have to buy a new copy of it? I guess my main questions are whether or not i'll notice any performance difference buying a g3 processor vs. a g4 processor doing basic things (homework, storing music/pictures, etc.)and is this is a good price for the above computer or one similar. I have no idea on what a reasonable price would be for something as described above. I don't really have much money to spend, $600 is probably my limit (for the computer itself, and a little extra for software). I'd love to be able to take a laptop with me to Europe my junior year of high school, but i really need something affordable. Thanks in advance for your replies!
