The following is based on a very few minutes of hands on tryout of an iPad at the Honolulu Apple Store.

Got my first look and try on the
Apple iPad at the Ala Moana Apple Store. It's a nice device that can do a lot of things like web browsing, book reading and purchasing, music playing, some movie viewing, youtube, word processing and office tasks with iWorks, photos and a more. It's bigger than an iPod Touch and Nintendo DSi, but smaller than most Netbook computers. It is not a full on computer as it cannot do things like flash or be connected to a wired network. It is a nice device that I may reconsider purchasing in the not so distant future.

The big problem I have with books and other content that is available for sale through the iTunes books, app and movie store is DRM. I was not given a very clear explanation as to whether or not the purchased, proprietory content can be easily transferred at no extra cost to another iPad or iPod Touch or iPhone that the end user may own. I was clearly told that book content from the iTunes store cannot be viewed on your regular Macintosh computer.
The nice thing that I found about book reading on this device is that you can turn the book in either the horizontal or vertical mode and that the fonts and type size can be adjusted to whatever you like. Pages turn seamlessly with a move of a finger.
There is a kindle app available for the iPad as well as other Apple hardware such as the Macintosh. Books bought from Amazon.com to play on the Kindle are not compatible with the book viewer that comes standard with the iPad. Again, DRM getting in the way.
While I did not try it, I was told by the salesperson at Apple that the iPad can also read PDF. There are a lot of public domain books as well as millions of other types of documents available online as PDF files, usually for free. But then again most every other computing device can read a PDF which means you don't need an iPad to view them.

The onscreen keyboard is nice and easier to type with than the ones on the iPod Touch or iPhone. A better choice would be an external keyboard which is available for the device.
One thing about the all touch interface... it leaves the glass surface of the iPad full of fingerprints and grease streaks from hands. A daily cleaning of the touch surfaces will be the order of the day.

There is a YouTube app that specifically plays any and all YouTube videos. Shown above is my video of a Hawaiian Airlines Being 717 landing in Honolulu Hawaii.
While the iPad does not do flash, it seems this app and a few others have managed to get around this limitation. There was an ABC app on the iPad I tried out that also lets you view video content from the ABC TV network.

iPad does iTunes, which means that it can play music, podcasts and other audio content as well as purchased video content from the iTunes music store. Funny how all the main features of the iPad is connected to you purchasing something from the iTunes store. I hope the music I already own and have on my Mac is transferable to the iPad.

Will I buy it? Probably will at some point. The iPad comes in two basic models of varying storage/memory sizes. All models are equipped with built in WiFi access. So if you have a home wifi network you're online. There are wifi hotspots in many places around major cities in the U.S.
The more expensive models have 3G wireles networking that you have to subscribe to from AT&T. The subscriptions are month to month and there is no long term contract. That is good. However the 3G prices are fairly high.
