i own an iBook 700 Mhz 256 mb 20 gig combo with OS 10.2.8 that i bought refurbished. i realized that i cant to a lot so i spent 30$ on ebay to buy 10.3 and i want to know a few things. is it worth upgrading? should i just resell the disk? can i still boot up OS 9 original? i really have nothing on here right now and if you know any good downloads or any suffestions let me know thanks.
