As of G5, i think they have superior hardware to anything presently available. I like that! In terms of OS they have that one nailed too.
The way they have married the hardware so well to the OS is incredible and makes for a very reliable , stable and fast systems.
Im not sure if its the hardware , OS, or what ever, but we have found that we can have more windows open at once running their tasks happily on iBook G4 than we can on centrino running XP.
Now undoubtedly per app the centrino is faster ... much faster! (comparing 1GHz G4 versus 1.7 Pentium M aint exactly fair deal! ) however, in terms of speed penalty when lots of apps are open at once and running concurrently, the ibook g4 seams much faster. This is one area that i do not know too much about , but could someone tell me if a RISC processor is more adept at havin many processes running concurrently than say an x86??? Or is this another consequence of the OSX factor being superior to win XP??
Any experts??
I know on a per app the Centrino is much much faster, just wehn different apps are run in parallel (i.e. real world) the ibook seams to really strut its stuff in comparison which is a bit of a shock! Personally i put this down to windows.
