I'm a long time Mac user and fanatic. I go all the way back to the Apple IIe up through my current 27" iMac. I also have an iPhone 3Gs and the new iPad (64Gig).
I'm hoping that the iPad will eliminate any need for me to take a laptop when I travel. I'm particularly interested in Keynote on the iPad any tricks or tips that emerge. I hope that the iWorks team will beef it up as time goes by.
