I have an iBook G4. 1.2ghz, 1256 DDR ram. 30gb hdd. I installed Xubuntu on it without even looking at OS X.
Canonical stopped support for powerpc around version 6.10 or 7.04. I used 7.10 and it worked well. I had wifi, compiz, sound!... it worked well. I uninstalled it because I want to consolidate my uses for computers to one laptop. Linux on my iBook wont easily allow me to synch my windows mobile phone. Nor can I use a comprehensive MaximDL type program.
So I installed Panther. I slowly warmed to it but MaximDL and MaxDSLR dont work on powerpc. I assumed they would work when I installed OSX. Schoolboy mistake! Nor would my camera be able to take exposures longer than 30secs cos Canon are awkward and make you buy a special serial lead. I can build one but the iBooks dont have a serial port.
I needed Tiger to install a similar inferior program (Nebulosity) So I downloaded it "just to test" during which time I lost my temper and decapitated my iBook with a right hook. Its now dead and I wish I sold it and bought a pc laptop. I only paid £100 for it about a year ago and they ebay for £300+
Im affraid my opinion of apple has reduced to "fashion accessory"
Not unless you are a graphic designer or something.
Xubuntu is still my primary pc. But I dual boot server 2003 cos im slowly working my way through the ms certs. Plus a laptop with vista dual booting xp. xp so i can login to the server 2003 domain. The vista/xp laptop is my girlfirends so its full of her stuff. I like to run a tight ship with my computers and having hundreds of mp3s, films, programs acer/vista/norton crap everywhere irritates me. With the ibook too I felt like I lived in 5 messy houses.
A new laptop with Xubuntu will do me. Dual boot XP for photography and domain login and my desktop for server2003.
