I've just finished preparing a decent-sized presentation with Apple Keynote 1.1.1 on my 1GHz 12" PowerBook with 768MB RAM (my G5 is away getting its video card replaced to solve its 'Black Screen of Death' problem). I've got the PowerBook running in lid-closed mode, with an external 19" CRT hooked up running at 1600x1200 and USB keyboard and mouse. One thing I will say...Keynote DRAGS on this machine. Everything from adding text, resizing including graphics or even just resizing the main Keynote window itself feels like it's dragging the PowerBook down to a sub-100MHz speed. I like Keynote...it's simple, and doesn't get in the way (plus the transition effects are cool). But its speed problems have put me off wanting to use it for anything serious again. Has anyone else experienced this? Is it the relative newness of the Keynote code, or is it just an yet another obvious sign that a 1GHz G4 really is on the trailing edge of CPU performance these days? Any Keynote gurus out there want to comment?
