One thing that shocked me on the iPad when I went looking for things I assumed were there because they're on the iPhone was that they arent there. There's no alarm clock on the iPad and there are no free ones yet that I saw. The iPhone has it, the iPod Touch has it but the iPad doesnt. What was Apple thinking there?
Also, in this highly visual touch device, the iPod app has no Coverflow support. Whats that about? Even the iPod nano has coverflow.
Then originally I had my email (google apps based) setup using the Active Sync approach. I found for email accounts setup this way you cant do anything at all when offline. I switched mail over to IMAP and it seemed to let me do some offline mail etc while I was on the plane.
For all that Apple has stripped functionality from the iPods and iPhone in delivering the iPad they've delivered little new other than using the larger screen space. In addition they've opted for up selling you on features that make sense for the platform like their iWork products.
It almost seems like the iPad is an experiment on how big a fan base they have rather than delivering a product that really is well rounded and meets market needs.
So yes, I skipped powering on my MacBookPro and it was a great video device on the plane but I still had to carry my MacBookPro with me because I the iPad isnt a computer, its an oversized, but stripped down, iPod.
