hey you macfreaks (i am, too!) i've been stuck with this 7500/100 (upgraded to g3 - 350mhz). i've been drooling over tibook for some while and i'm relatively new to this forum. i cudn't seem to find a thread that would tell me about the possiblities of next speed bump for tibook before i can purchase it. i just want to ensure that my $$$ will be invested on the best tibook ever (but i really don't want to be a sucker when i buy a g4 667mhz tibook today only to see its price slashed when its new high end comes out next week!!!) your scoops wud be very appreciated!!
