Ok, what will I lose and what will I gain by upgrading from my current 10.3.9 system to 10.5, or even just to 10.4.x?
I'm terrified of losing data or compatibility. Will the fancier graphics in 10.4 and higher slow down the GUI (it's already pretty terrible in 10.3).
My system is a PM G5 Dual 1.8 GHz, 1 GB RAM and an ATi Radeon 9600 64 MB gfx board.
Even though I was an Apple tech support agent five years ago, I've very little interest in computers other than as a tool. It took me almost half a year to find that 10.4 was released when it was. I'm not a power user. I haven't even changed the background picture from that blue arc thing.
