I know I'm ignorant; I know I'm a recovering PC user. Please, if you need to take a few cheap shots, feel free Vista ran me away from PCs for _good_. Actually, constant crashes and the gift of an antique iBook got me off of PCs. I now have the old beat up iBook and one of those aluminum iMacs. I know also that the iMac is apparently rather looked down on, but really, it was almost perfect for me: it's like the world's nicest lap top, only not portable. At any rate, I had a major issue with a Safari update on my iBook (which I had affectionately dubbed "the Road Apple" until I learned that this is something of an insult amongst Mac users.-- hey, I'm new at this, remember? ) At any rate, the battery is really on it's absolute last legs on my venerable machine, and I'd like a bit of help learning what this thing is so that I can begin the hunt for a battery. All I can really say right now (because I don't know what to look for or what to tell you) is that it's a clamshell with a nifty built-in handle, it's white with fluorescent green "trim (?) and a white keyboard. It features a _bizarre_ power adapter that I have learned is referred to as a "yo-yo." the "About this Mac" button gives me this: Mac OSX 10.4.11 Processor 466 MHZ PowerPC G3 Memory 576 MB When I click "more info," it tells me this: Machine name: iBook Machine Model: PowerBook 2,2 [yes; it's a comma] CPU Type: PowerPC 750 (22.2) [a period; not a comma] Number of CPUs: 1 CPU Speed: 467 MHz L2 Cache (per CPU) 256 KB Memory: 576 MB Bus Speed: 67 MHz Boot ROM Version: 3.3.3f3 Then there's the serial number and the Sales Order Number. Is there anyone who can give some idea of just what of all this I need to know to battery shop, and maybe some idea of the actual vintage of this machine? I'm sure it's old and outdated, but I _love_ this thing; it's stood me in great stead for some time now, and even though I _know_ those hardware specs are decrepit (at least from a PC perspective), this thing has consistently outperformed my PC (except in speed, but again: low numbers) and still outperforms my wife's new PC-based Dell netbook in everything but graphics. I love this thing, and I want to keep it going as long as I possibly can.
