My goal, once I receive my iPad 3G (someday.... someday....), I plan to see how far I can push that sucker to replace what I do with my MBP. I have a theory and I realize my theory may be laughable to some, but here it is: Steve Jobs and Apple are not pitching the iPad as a laptop replacement because they still sell a bunch of MBs and MBPs. As a first generation device, the iPad isn't completely ready for that anyway. But... I believe that Steve-o very much believes that the iPad is not truly a 3rd category -- it will one day be the device that replaces laptops. I'm wearing my asbestos suit in preparation for the flaming
I really do not want it to replace my laptops; I have three. I like them. I like what they do and how they do it. When I had no alternative, I did not even mind carrying them, not even the 7 pound Toshiba.
I just noticed that, even when in the same room with laptops, I often preferred the iPhone. I discovered Air Mouse and found that the iPhone was a good way to operate the laptops. Then I discovered LogMeIn Ignition and found that I did not have to carry a laptop at all.
So, what I want the iPad to do is give me one more choice about what to carry and how to do my applications. Of course, I am still waiting for Apple to ship so I am not quite sure how well it will work, but I am pretty sure that I will not carry a laptop on any trips less than a week after I get my iPad.
