This iBook G3 ...
... is my sole and only workhose right now. It´s getting slowler, but still I can get so much productivity out of it. Basically it smokes most of the computers of my friends, not speedwise, of course.
I pimped it myself to a 80GB harddrive and a Toshiba 8x double layer superdrive. It´s a G3 500 Mhz CPU with now 640MB RAM, a Lucent Wavelan hacked Airport Card and bluetoothed via D-Link USB Adapter. It runs very well together with OSX 10.4.3.
Because of all the mods I am basically now fluent in opening iBooks. My personal record is a mere 4 min, stripping of all the casings and shieldings.
It is recording DVB-C MPEG streams from a Sagem DBox 2 with Neutrino Linux via Ethernet, handles all my photoshopping, my mpeg editing, my dvd processing and music recording via a Soundblaster mp3+ usb box and Logic Express, which does work quite handy somehow. And internet browsing, word processing in small and huge quantities, scanning, my photo collection, data mining etc. pp.
Without it I truly feel naked. It never gave me any failure (only third party stuff like harddrive and dvd drive passed away).
It´s 4.5 years old. It earned a name. I´ll never ever leave it behind, but will repair it by any means and you´ll only be able to pry it from my dead cold hands, anyone?
