I hear it is possible to change the motherboard to a better g3 one? I even hear it is possible to use a g4 one but I really am not sure, I too have an ibook 500 and was wondering if my local apple store could upgrade me to a g4 for less the price of a brand new one. Any suggestion?
"upgrading" the motherboard is not practical. Go buy an newer computer. A laptop is not like a desktop PC where you can easilty open it and easily exchange parts.
All iBooks have the same speed ethernet and most (I think!) iBooks can use the faster airport extreme. So a faster processor iBook doesn't help in this department.
If you have 512MB RAM upgrade already then the next best thing you can do to improve performance is upgrade to OS 10.3 (aka Panther). 10.3 runs noticeably faster than eariler versions.
Next, look how much disk space you have left. I think the 500MHz iBook has a 10 or 20GB drive. If you have no more than about 3 or 4 GB left, time to seriously flush junk from the drive or get a new one. The OS uses disk space for "virtual memory", and it uses several GB of disk space for it. How much depends on lots of factors like how much real memory you have, how many open apps. You can mitigate this issue by not opening lots of apps at one time. If you see lots of hesitation switching between apps or perhaps an app just "stalls" for a few seconds, then this could be a symptom of too little RAM and/or virtual memory disk space. This happens on my PC at work all the time!!
Now a hard drive upgrade is doable, but you must take your iBook apart to do it. There are clear instructions available on the internet. Do a search. I'd bet the Apple store or CompUSA and others can do it for a fee.
bottom line
If you feel compeled buy RAM, buy a new drive, and buy a new OS you might as well buy another computer w/ them already installed; and sell this one. OR just accept what you have and live w/ it until you really can afford a new(er) iBook. The Macintosh experience is WAY better than PC at any speed!
